Cannabis Events 2019

2018 was a busy year for cannabis, with important events like the legalisation of adult use of cannabis in Canada and the legalisation of hemp in the USA. These events undoubtedly had a profound effect on how cannabis is viewed around the world. The number of countries implementing medical cannabis laws is growing, even in the Asian region, as countries such as South Korea, Thailand and Malaysia are implementing medical cannabis legislation.

2019 is looking to be even bigger. If we look at the ever-growing number of cannabis related events happening this year, we can see a trend of exponential growth of business conferences, expos and hemp events. With so many event happening all over the world, it is essential to have an overview of all the major events happening each month in different countries.

If you are interested is specific regions, below are the links to posts that cover EU, Canada, USA and Latin America.

For a general overview of all the world cannabis events, you will find them below in chronological order. This way, you can choose which events to attend all year around (the dates are in DD.MM.YEAR format).













There will certainly be many more cannabis events announced during the year and I will add them accordingly. If I missed any relevant 2019 events, please let me know in the comments, so I can add them to the list.

USA Cannabis Events 2019

2019 is going to be one of the busiest years for cannabis in the USA, as is confirmed by the increasing number of cannabis related events happening in different parts of the country.

Last year’s legalization of hemp will have a huge impact on the number of hemp related events and will undoubtedly be a crop that many farmers looking at for its economic benefits and multipurpose use. There is an increase in business conferences and CBD related events, while the scientific conferences are still a few, but very professionally organized.

California is still the leader in the number of cannabis events, but other states are following and we are seeing events popping up all over north America. I you are interested in other cannabis events happening on the American continent, check out the Canadian Cannabis Events 2019 and Latin America Cannabis Events 2019 posts.

Below is a list of all the major USA 2019 cannabis events in chronological order (the dates are DD-MM-YEAR) with links to events official website. This is not a full list, as there will be many more events happening, especially during the second half of the year. I will be updating this list regularly to include all the missing events.











With such a huge influx of cannabis events it won’t be difficult to find an event that suits your needs and is close to where you live. 2019 will be a great year for cannabis and hemp and I am looking forward to seeing how this industry develops over the next few years.

If I missed any relevant cannabis events, please let me know in the comment section, so I can add them to the list.

Canadian Cannabis Events 2019

Last year’s legalization of adult use of cannabis will undoubtedly have an effect on the number of cannabis related events in 2019. Canada is becoming a world leader in medical as well as recreational cannabis production and is in a way showing to the rest of the world, how to implement a professional and standardized cannabis market.

Most of the cannabis events are business related, with expos also having their part in the normalization of cannabis as a consumer product. There is a striking lack of scientific conferences, which should be addressed, as these types of events are the basis for scientific credibility of the cannabis plants potential therapeutic applications.

Below is a list of all the main 2019 Canadian cannabis events published so far. I am sure that more events will be announced as the year progresses and will add them as soon as their websites are live.

Masterclass Medicinal Cannabis 2018

2018 was an eventful year for Canada; not only did they legalize recreational use of cannabis but the Masterclass Medicinal Cannabis took place for the first time outside of Leiden. This was a great opportunity to share valuable information about all aspects of medical cannabis to Canadians and anyone else who was willing to join us in from the 28th of October to the 2nd of November in Ottawa.

For those who are not familiar with the Masterclass Medicinal Cannabis, it is a 5-day intense course on all aspects of medical cannabis presented by some of the most renowned cannabis experts. As Dr. Arno Hazekamp, the founder creator of this course, likes to put it; it is a guided tour into cultivation, research and development of medical cannabis, a meet and greet with diverse professionals, and a place where you can ask questions, share insights and learn from other cannabis enthusiasts.

Ottawa, here we come!

The timing of the Masterclass was strategically planed, just a 2 weeks after Canada just legalized the recreational use of cannabis. Now, one expect that this meant you could legally buy cannabis in specialized shops – one would be wrong. To my surprise, the local government decided to only allow the selling of cannabis trough online stores, as brick and mortar stores would be allowed to operate only from April 2019. Despite these limitations, as predicted by many, there was a shortage of cannabis and cannabis products, and most shops, that actually were allowed to sell, run out of products in just a few days. We have seen this scenario happening in many times and yet nobody seems to learn from it.

The venue was the Novotel hotel, situated in downtown Ottawa right next to a labyrinth 4-story mall, where I got lost a few times, and the delightful ByWard market, full of restaurants, delicatessen and grocery stores. The weather was a bit gloomy, not ideal for sightseeing but good enough for keeping us in the classroom, where the learning commenced.

The program

The Masterclass is divide in to 5 main sections or the 5 P’s; Plant, Product, Patient, Physician and Policy. Each presentation was talking about one of the 5P’s

From top left to right: Dr. W. Brent R. Pollock , Nick Pateras and Dr. Ernie Small

This year we had the opportunity to listen to learn from some of the most influential cannabis experts (Dr. Ernie Small, Dr. John McPartland, Dr. Jahan Marcu), with a particular emphasis on Canada, as many presenters were locals (Prof. Lakshmi P. Kotra, Dr. Caroline MacCallum, Dr. W. Brent R. Pollock ), who provided us with specific insights on the Canadian cannabis situation (Mike McGuire, Dr. Bruno Battistini).

From left to right Dr. Bruno Battistini, Dr. Chris Spooner and Dr. Caroline MacCallum

Of all the great presentations and presenters, I will mention just two that stayed in my mind; Dr. Mike Dixon and Dr. Chris Spooner.

From left to right: Tal Lupo , Yewande Okuleye and Mike McGuire

Dr. Mike Dixon took us on a journey into the future, as alluded in the title of his presentation “Applications of Space Exploration Technologies in Medical Cannabis Production”. Most of us already know, that for producing standardized medical cannabis (cannabis flos), it has to be grown in a closed environment where you can monitor all the environmental aspects and achieve homogenous growing conditions. This is due to the fact that phytocannabinoids and terpenes are secondary metabolites, that the plant produces as an adaptation to environmental factors. Mike has taken this to another level with the help of space technology to finely tune and monitor, every aspect of plant growth and the impacts these changes can have on plant morphology and the production of secondary metabolites. Light, CO2, oxygen, nutrients, water, temperature, and air quality, are all important factors, that can be modulated, to achieve stability and maximal yields of the desired constituents. It was fascination to see, how different wavelength of light, in different areas of the plant, had such a profound effect on the production of certain cannabinoids, terpenes and terpenoids. I am confident, that the implementation of this type of technology will greatly improve the standardized medical cannabis quality.

Dr. Chris Spooner presentation “Integrative Cannabinoid Therapeutics” gave us an insight into the endocannabinoidi system as a master regulator of our body’s homeostasis and how, via different mechanisms, we can help it in its important task. Several studies have shown that nutritional deficiencies can impair ECS function and integrating omega-3 fats, vitamin d and methylated B vitamins, can improve the overall efficacy of this crucial system. The gut microbiome also has an essential role in health, as these beneficial microorganisms have important roles in various aspects of our health. It is refreshing to see a doctor with such a holistic approach and I wish more physicians would embrace this kind of integrative treatment, that has been successfully used for centuries but was systematically eradicated and replaced by modern age allopathic treatment.

The information that all the presenters delivered was highly appreciated by the class of 2018 and they also had the possibility of continuing the conversation with the speakers, further deepening the knowledge of all the interesting cannabis subjects.

Filed trip to Smith Falls

The last day of the Masterclass is reserved for a visit to a licensed producer. Usually the visit was to Bedrocan’s facility in the Netherlands, but this year, being in Canada, we visited Canopy Growth and its facility in Smith Falls, just an hour away from Ottawa.

Bruce Lipton, the CEO of Canopy Growth at Smith Falls
The visit to Tweed

Bruce Linton , the CEO of Canopy Growth, introduced us to the Canopy’s beginnings, its current situation and future plans. We had a tour of the various rooms, where cannabis is cloned, grown and made into its final products. We also took a tour of the Cannabis museum, where I found myself teaching the guides about the ECS, cannabinoids, terpenes and their interactions.

Being the last day of the Masterclass, we had a farewell dinner, where besides having a great time, the students of 2018 also got their certificates, officially adding them to our Masterclass family.

Conclusion and MMC 2019

Once again, the Masterclass 2018 was a fantastic event, a gathering of old friends and new acquaintances, full to the brim with interesting information, people and a time to enjoy likeminded professionals with cannabis as the glue that held it all together.

What about the future? The Masterclass Medicinal Cannabis will return in 2019, this time expanded to both continents.It is still too early to divulge the details so be sure to follow this blog and the Masterclass page for updates.

THCV – The skinny cannabinoid (part 1)

THCV – Tetrahydrocannabivarin

Cannabis sativa: The Plant of the Thousand and One Molecules“ is the title of a paper by Andre et al. which eloquently shows the complexity and immense therapeutic potential of this plant. Cannabis sativa L. is most known for its cannabinoids and is the only plant that produces them in such high quantities. [1]

Besides phytocannabinoids (plant-cannabinoids) there are a vast number of other compounds such as terpenes, flavonoids, strereoids and fatty acids that all together have a synergistic effect on the efficacy of cannabis therapy. [2]

In the past, most of the research has been concentrated on the psychotropic compound delt-9-tetrahydrocanabinol (THC), while other „lesser “cannabinoids have been mainly overlooked. One of the overlooked minor cannabinoids is THC’s little brother, (THCV).

The two cannabinoid families

There are two major cannabinoid “families” that dominate the cannabis plant and the difference is only in 2 carbon atoms. The pentyls have a phenolic sidechain of five carbon atoms, while the propyls have only three. This difference is due to two different acids being used in the synthesis of phytocannabinoid precursors. If olivetolic acid is combined with geranyl pyrophosphate, we get cannabigerolic acid (CBGa). CBGa can then be converted to other cannabinoid acids depending on the acid sythethase that is present. THCa sythethase transforms it into THCa, CBDa synthethase into CBDa and CBCa synthethase into CBCa.

If instead of olivetolic acid, divarinolic acid is combined with geranyl pyrophosphate, we get cannabigerovarinic acid (CBGVa). The same acid synthetases that convert the pentlys also convert the propyls; THCa sythethase transforms it into THCVa, CBDa synthethase into CBDVa and CBCa synthethase into CBCVa

The discovrery of THCV

THCV was fist isolated in 1970 by Gill et al. by extracting it from a licensed cannabis tincture, that was available in UK at the time. The tincture was legally imported and made from Pakistani grown cannabis. The tinctures main constituents were THC (2,4%) and THCV (2%), an interesting 5:4 ratio, that can also be found in newer chemotypes (Doug’s Varin). [3]

As a side note, the propyl analog of CBD, cannabidivarin (CBDV) was isolated, as so many other cannabinoids, form hashish, by Vollner et al., in 1969. [4]

High THCV chemovars

THCV is inherently rare in the usual cannabis “strains” and it has been difficult to find chemovars with high percentages of this cannabinoid. Higher levels of this cannabinoid have been usually found in certain Asian and African landraces.

GW Pharma has developed their high THCV strain from selective inter-breeding of high 1:1 THC: THCV landraces (China, South Africa) and named (California orange, Malawi Gold) chemovars. By a selective process of self-pollination and cross breeding of the phenotypes with the highest levels of the propyl cannabinoids, they obtained a genotype with 96% of total propyl cannabinoids. [5]

One of the most well-known chemovars, with a high THCV, is the appropriately named Doug’s Varin. In tests done by Steep Hill Labs, they detected 19 % THC-A and a whopping 15% THCV-A. The main terpenes were beta-myrcene 1,5%, pinene 0,53 and limonene 0,48. They also performed an analysis on decarboxylated kief of this chemovar, and they measured 24,25% THCV and 21,13% of THC. The only measured terpene in the decarboxylated kief was beta-myrcene (0,38%), which shows us, how the monoterpenes are lost during this process. [6]

Recently, some chemovars have tested higher THCV values such as Jack el frutero (6%), Jack the Ripper (6%), Pink Boost Goddess (5%), and Black beauty (3-4%).

There might be other chemovars containing higher percentages of THCV, but sadly, a lot of analytical laboratories, still do not test for the presence of this cannabinoid.

THCV part 2

In the second part of this 2 part THCV article, I will be tackling the important question of THCV’s psychotropic effects (or lack thereof), its potential therapeutic applications in various diseases and if it really is the “skinny” cannabinoid.

Cultiva Hemp Expo 2018

Cannapa in Mostra, 26-28 October, Naples, Italy

The association CANAPA in MOSTRA is pleased to present CANAPA in MOSTRA International Trade Fair of Industrial and Medical Hemp of Naples.

Hemp, known and used in all parts of the world, is recently returning to make space through a renewed social and economic interest.

In particular, we propose hemp as an ecological resource in the agricultural, energy, medical, recreational, textile, paper, green building and in every other possible field of application, trying to undermine the socio-cultural prejudices that oppose its real and massive reintroduction in the Italian context.

The fields of use of this plant are already very many, but with the advance of technology and scientific discoveries could become infinite, moreover the continuous demand for new eco-sustainable technologies imposes the need for new research on this extremely versatile material.

The intention of the association is to bring the general public and institutions aware of this potential and to bring to mind the long tradition that links our country to hemp, particularly the Campania region, trying to provide a place for aggregation , training and exchange for workers, experts, enthusiasts and anyone who is intrigued by this re-emerging industry in continuous turmoil and expansion.


Cannafest, 2-4 November, Prague, Czech Republic

The international trade show of cannabis and medical herbs Cannafest is the biggest cannabis fair in the world. Visitors can look forward to interesting expositions of exhibitors from all around the world. As usually, there will be cultivation technology, fertilizers, seeds, smoking accessories and vaporizers on display and on sale. People could also try and buy various hemp cosmetic products, clothing items or delicious hemp food, which shouldn’t be missed.

We are expecting again more than 300 international participants from more than 40 countries – we are looking forward to the biggest event on industrial hemp ever!


How much  ∆9-THC is in cannabis flowers?

The cannabis plant produces cannabinoids in the form of acids, like delta-9-tetrahydrocannabinolic acid (∆9-THC-A). It does not enzymatically produce a single molecule of delta-9-tetrahydrocannabinol (∆9-THC). That does not mean, that there is no ∆9-THC in the flowering tops; ∆9-THC-A and other acidic cannabinoids get converted into their neutral forms via heat, light or exposure to oxygen.

The presence and ratio of acid: neutral cannabinoids can also be an indicator of storage and age of the analysed cannabis. Improper storage can decrease the level of acidic cannabinoids, which in turn increases the level of neutral cannabinoids. Other volatile compounds, such as monoterpenes, are also susceptible to improper storage.

By doing a quick search and calculation from 15 analysed samples of type 1 (high THC) from Analytical 360’s archive website [1], the average ∆9-THC (compared to ∆9-THC-A) was 7,1% (2,4 – 12,4, n=15). From 5-10% of the total THC is usually in the neutral form, in properly stored cannabis.

If we compare this data to a study by Wang et al. [2], where they analysed DEA confiscated samples and samples from the University of Mississippi, the average % of ∆9-THC was 33,2% (19,2 – 54,7, n=11) in the DEA samples and 28,5% (10,5 – 41, n=6) in the Mississippi samples. While the number of samples analysed is relatively small, it can still give us an indication of the storage and handling of the plant materials.

Even worse results can be seen in a recently published study by Souleman et al. [3], where they analysed confiscated cannabis flowers and hashish. In the flower samples, 80% of the total THC was in the form of ∆9-THC and only 20% of ∆9-THC-A.

Another usually used indicator of cannabis poor storage is cannabinol (CBN), the oxidative product of ∆9-THC (or CBN-A). The samples form 360 analytical had no detectable CBN, while all the DEA samples had CBN present, on average 0,79 % (0,18 – 1,44, n=11). Only 2 of the 6 Mississippi samples had detectable CBN and no information on CBN levels was included in the Egyptian study.

In the discussion section of the same study they also commented that “marijuana, has shown a higher THC content than we expected based on the world drug reports.” If we compare the 11% total THC that hey reported, to the other newer published studies 12% [4] 13.9% [5] [ 14.88% [6], we can see, that it was in the lower end of potency for today’s standards.

A more indicative report, of the potency of the cannabis present on the market, can be gathered form analytical reports from laboratories. As an example, in the 15 samples analysed by 360, the average of total THC was 18% (13,25 – 23,22, n=15).

2nd annual Terpestival™ 2016 Hopland, CA

On the 23rd of July The Center for the Study of Cannabis and Social Policy (CASP) organized the 2nd annual Terpestival in Hopland CA.

The festival’s main goal is to  was designed to educate the public on the contribution of terpenoids to cannabis plant-based medicine. The keynote speaker was Dr. Ethan Russo who had a presentation entitled “Terpenoids and Cannabinoids.” There were several interesting panels all concentrated around the importance of terpenes in the hemp plant.

Total Terpene Aggregate Results

As the name suggest, in the The Terpene Tournament™,  the terpens were the stars of the show while cannabinoid content was not so relevant. All the flowers and CO2 concentrates were tested to determine the cannabinoid and terpene content. The  average flower terpene content was 1.4%, due to the loss of terpene content from harvest time. The average terpene content in concentrates was 9,7%.

An important take-away message from the event was that cannabis shouldn’t be defined only by the cannabinoid profile. Terpenes and other aromatic molecules give cannabis its distinct taste/smell and are very important not only for their medicinal value but also for the enhancement of the connoisseur experience. You can find more info on the event here.
