friend of my from jamaica smoke it like all his family. he explained that msot of people there smoke weeds and that's better than pljeskavica
It's different to talk only about weed or about all the drugs though buddy
I think we should not even mention weed in this thread because this "drug" might "fuck you up" only if you use it too much (like several times per day) and even that can't be compared to the harm to your health from using heroin, crack, meth or another hard drug.
Technically, weed has a lot of negatives. And positives. It's helpful for some things but comes at its costs. The best way to relate it is being like a medication -- it may help some problems, but it causes others. Think Aspirin and ulcers, for example.
