Cannabis consumption
（重定向自Wake and bake）
Among the variety of ways cannabis is consumed forms of smoking or oral consumption are most common. Each method leads to subtly different psychoactive effects due to the THC and other chemicals being activated, and then consumed through different administration routes. It is generally considered that smoking, which includes combustion toxins, produces a somewhat more relaxing ("stoned") effect, while eating delays the onset of effect but the duration of effect is typically longer. In a 2007 ScienceDaily report of research conducted at University of California–San Francisco, researchers reported that vaporizer users experience the same biological effect, but without the toxins associated with smoking marijuana.
