See now that's where you're somewhat wrong. The chemicals inside of marijuana are the things that help you, smoking it is one way of extracting it. Cannabis oil does the same thing, health wise, but without the extra release of dopamine. To go along with this, your receptors can get worn down because of this intense excretion of dopamine. When it [i]does[/i] get worn down, it can and will put you in a certain specialized state of depression. In my own opinion, only cannabis oil should be legal, not the plant itself.
