Marijuana has been shown to cause brain damage by major medical schools.It’s also been shown to cause lung damage...again,major medical schools.
Alcohol and tobacco have been shown to cause damage; what ought we do about that?
As I keep on telling the potheads, there’s overwhelming evidence out there that dope causes major mental problems and brain damage, but they never listen. The synapses are gone. The first thing drug use does is overwhelm the portions of the brain used for self-control and reasoning, and then it is downhill from there.
