WEED ~ Cannabis sativa
1 joint=pack of cigarettes. I remember this one from 6th grade, that smoking a joint had as much evil and tar as 1 whole pack of smokes. Well it’s bullshit. It is oft repeated that cannabis smoke has a higher chance of giving you cancer but that is simply not true. While tons of pot smoking may lead to bronchitis and other respiratory ailments, there is little evidence that pot alone can cause lung diseases like emphysema that are generally linked to cigarettes.
