From what I can say from experience - Psychedelics make you aware of the internal sensation of the body a lot. So smoking actually gives you a negative feeling as opposed to the usual feeling. This negative reinforcement is really useful for kicking the habit. Same with alcohol or even meat products in particular. You can feel becoming stupid eating those. I think microdosing for 30 days is an effective way of kicking off habits or forming new healthy habits.
