hmm i wouldn’t say that most teens are doing it, but of course there’s always a group doing drugs in every community. i’d agree and say that marijuana is the most popular because it isn’t very expensive, but in richer neighborhoods, people abuse more expensive drugs like percocet.
In my area it's very common. It's legal for anyone over 21, but like drinking, most teens do not care that they are under the age of the law. A lot of adults use marijuana too. In the city you can smell it quite often as people just smoke in the streets sometimes.
