The legal cannabis industry in Asia is growing fast. Most growers, suppliers and labs still talk to each other on general social media apps. Those apps were not designed for this crop, and that causes real problems.
This topic explains three things. It covers what goes wrong on general social media, what the forum offers instead, and what Thai law allows you to post here.
Why cannabis posts disappear on social media
Facebook and Instagram check posts with automated content moderation. LINE does the same in its public areas, but not in private chats. This means software scans your text and images and can act on them without a person reviewing them first. Cannabis posts often trigger this software, even when the content is fully legal under Thai law.
Three things can then happen to you:
- Shadow-ban: the platform hides your post or shows it to far fewer people, and it does not tell you.
- Locked account: you lose access, and your old posts and contacts go with it.
- Rejected ads: the platform refuses your paid posts.
Translator’s note: Many Thai grower groups run on LINE and Facebook. In a busy chat group, a good answer scrolls out of sight within days. Later, nobody can find it with search.
What to do: Next time you write a long, useful answer in a chat group, post it as a forum topic as well. Then share the link in the group. The group still gets the answer, and you can find it again later.
A forum built for the legal cannabis community
Asiannabis is a forum for people working with legal cannabis and hemp. Posts are sorted into categories, such as cultivation, pests, nutrition and compliance, and they stay in those categories.
Knowledge that stays searchable
You can share growing experience, pest management, plant nutrition, and the steps for working to certification standards. Two common standards are GACP and GMP. GACP is the standard for growing and harvesting medicinal plants. GMP is the standard for manufacturing medicines and other regulated products.
Posts stay in the forum archive and you can find them with the forum search. That does not mean there are no rules. Moderators, helped by automated moderation tools, remove posts that break the Community Guidelines or Thai law.
What to do: Search the forum before you post a question. If your question is new, list your substrate, light, temperature, humidity and province. Readers can then compare your conditions with theirs and give you answers that fit.
Finding the right people in one place
Producers, distributors, legal consultants and testing laboratories are all on one platform. Testing laboratories are labs that measure cannabinoid content and check for residues. You no longer have to search through thousands of Facebook groups to find the right partner.
Useful places to start are the Vendor Directory, B2B Services for labs and logistics, and Consulting Services.
Translator’s note: Finding a contact online does not prove they are reliable. Clones bought from another farm can bring pests, hop latent viroid (HLVd) or the wrong strain into your room. HLVd is a tiny pathogen that spreads through cuttings and tools, and it often shows no symptoms at first. For seed sellers, see how to vet a Thai seed vendor.
What to do: Ask any new supplier for their licence before you buy. Keep new plants in a separate area and inspect them before they go into your main room. This way you catch pests and disease before they reach your whole crop.
Building a track record under your name
Every post and answer you write stays under your profile. Over time, other members can see what you grow and how you solve problems. On social media, an ad filter that flags one post can cost you your whole account history. Here, moderation decisions are made by the forum administrators. Accounts can still be suspended for breaking the Terms of Service or the Community Guidelines.
Businesses have their own places on the forum. The right places to talk about your own company are the Marketplace and your own member sub-forum. To get a sub-forum, you email a request. The admin team checks it and then creates a sub-category for you. See List Your GrowShop or List Your Farm.
What to do: Add your region and the crops you grow to your profile. Then answer one question in an area you know well. Readers can then weigh your advice against your conditions.
Nine languages
Content is published in nine languages: Thai, Vietnamese, English, Chinese (Simplified and Traditional), Russian, Japanese, Korean and German. The aim is to serve growers and businesses working across borders in the region.
What to do: Write in the language you write best. In your first lines, give your country, province and the current season. A grower in another country can then tell whether your results apply to them.
What Thai law allows you to post
The forum operates under the Notification of the Ministry of Public Health of Thailand on Controlled Herbs (Cannabis), B.E. 2568 (2025 CE), and the other regulations now in force. You can share knowledge and discuss business here, within the limits below.
Translator’s note: Thailand uses the Buddhist Era (B.E.) calendar, which is 543 years ahead of the Western calendar. The main rules that affect posts are summarised below. For the full history, see Thailand’s cannabis rules, 2022 to 2026.
| Rule | In force | What it means |
|---|---|---|
| Notification on Controlled Herbs (Cannabis), B.E. 2568 (2025), issued under the Thai Traditional Medicine Protection Act B.E. 2542 (1999) | 26 June 2025 | Cannabis flower is a controlled herb. It may be sold only with a PT 33 (ภ.ท.33) prescription covering at most 30 days. Advertising flower and selling it online are prohibited. |
| Ministerial Regulation on Cannabis or Hemp Extracts, B.E. 2569 (2026) | 26 April 2026 | Licences for extracts above 0.2% THC go only to state agencies, the Thai Red Cross Society, and Thai juristic persons (registered companies or other legal entities) that are not “foreign” under the Foreign Business Act B.E. 2542 (1999). |
| Ministerial Regulation on Controlled Herbs (No. 2), B.E. 2569 (2026) | 30 April 2026 | Tightens the licence criteria for cannabis flower. |
Section 78 of the 1999 Act sets penalties of up to 1 year in prison, a fine of up to 20,000 baht, or both. For details of the two 2026 regulations, see what changed in April 2026.
The draft Cannabis Control Act is not law yet. The Cabinet approved the draft on 22 September 2026 and sent it to the House of Representatives. See where the draft stands.
The ban on advertising flower and selling it online applies to the whole forum. It also applies in the Marketplace and in member sub-forums. If you grow outside Thailand, your own country’s law also applies to you. See cannabis laws across Asia.
What to do: Before you post about any product or service, read what you can and cannot post on Asiannabis. Never post flower for sale, flower prices or delivery offers. This protects your account and keeps your posts within Thai law.
How the community works best
A community is strong when its members help each other. That means sharing what they know, recommending reliable partners and warning each other about risks. The forum is set up so that you can do this without a platform getting in the way.
Four things you can start this week:
- Introduce yourself in Introduce Yourself. Say where you grow and at what scale, so others can match their advice to your setup.
- Start a grow log in Grow Diaries. Record temperature, humidity, feeding and yield, so you have numbers to compare against on your next run.
- Warn others about risks. If you see a pest outbreak, a fake product or a scam, post it in the matching section. Growers in your region can then act early.
- Recommend partners you have checked yourself. When someone asks for a lab or a consultant, name one you have worked with and say what they did for you.
