I'm chinese. it's plant which may exist beform human being,all the culture use this shit,we do so,like in TCM,we seen it as medicine,the leafs,buds,even use it's roots.it's all cool and legal.
but for smoking, fuck! we have a very strict drug policies,and powerful conscious control with publicity.so many people have bad attitude and few knowledge about drugs.people don't know it could smoke,even some cop don't know either. but actually we have many wild weed growning outside...if you don't smoke,it's cool,if you take them home,then you will be caught...
i live near by tibet,i like riding bike on country,so i find so many wild weeds,it's looks like some kind of sativa,tall and narrow leaf,about 2 meter,sticky and some purple,i bring them home, but unlucky, it have few effect, even it's smell and sticky, but it can't get you high. it's more like very poor indica, you can get red eyes ,heart beat,cotton mouth but not high,even under the large dose.
china have no hippie culture, people afraid of drugs,we have many monitor on road and webs are also not privacy.so we have no soil for hippie culture growning,we even have no soil for any culture growning. censorship and capitalism sucks,they can ruin every things.
if you are on your travel and wonder to know some somkers, maybe you can go to yunnan dali and xinjiang.Muslim smoke pots,but they are closed,you won't like play with them,they also won't tell you they smoke,but you can always find wild weeds on Muslim area. yunnan have some hippie, but yunnan is a risky place, because of drug problem, they are under so many attention.
we have no drug culture, so our wild weeds may sucks, at least all i found are sucks
