best bet would be by the type of high you get....and for the most part Sativa buds are long and fluffy and Indica are more dense and small...

also if your guy knows the true name of the herb hes selling, you can look it up online... most seedbanks tell you what percentage of Sativa and Indica are in that strain... But for the most part bud is a mix of the two...ie 60/40, 80/20
nomadherbman Reviewed by nomadherbman on . Getting disappointed with weed. I like the feeling weed gives me, its like the NO2 at the dentist, i feel a little lighter, a little absent, I walk like a drunkard. But I don't experience the same of what you guys are describing here. Last night I had to get 10 hits to experience the slightest visual effect, and that was that everything was blurry, like being drunk. And that only lasted for about 10 minutes at the very beginning, and it was just back to being a regular high. And music doesn't really sound any different. Rating: 5
