Can you smoke and drink in Grand Theft Auto San Andreas?

CJ does not smoke in GTA San Andreas, apart from being unable to avoid inhaling fumes from a field of "weed" he is burning for The Truth in a mission, and when Truth lights up a spliff in the Mothership. The only time he is seen to drink alcohol is in cut scenes with friends and girlfriends. He does not have access to booze otherwise, like Niko does in gta IV.
