My psychology book actually refers to marijuana as the safest abused drug in America, safer than alcohol and tobacco. It says that while it is unsafe to drive or operate heavy machinery while under the influence, there are very little long-term and short-term affects. In fact, its effects are described as very subtle, and a person who has used other hallucinogens might think that smoking cannabis has no psychoactive affect at all.

Baby steps, man. Baby steps.
