It might possibly be better for people to buy drugs from home, over the internet, than having people go to street corners, in bad neighborhoods, after dark, to buy drugs.
Yeah I'd say it's a lot safer to buy your drugs online, certainly if you live in the US, where drugs are being sold by people (gangs) who carry guns.
Even in Europe, where drug dealers are less likely to carry guns, you'd probably be safer buying online, since the chances of getting busted are lower by buying online.
I'm saying this based on anecdotal evidence, so it might not be the case that all drug dealers in the US are part of a gang or carry guns, but it just appears to me that buying drugs in Europe is generally safer than buying it in the US.
