so does drinking, and I dont see anyone here outcrying against drinking. It should be legalized but regulated like tobacco and alcohol so kids can't get into it. in closing: If you enjoy it, use it.
Q: What does marijuana do to the brain?
A: Some studies show that when people have smoked large amounts of marijuana for years, the drug takes its toll on mental functions (4). Heavy or daily use of marijuana affects the parts of the brain that control memory, attention, and learning. A working short-term memory is needed to learn and perform tasks that call for more than one or two steps.
