You could end up never finding a strain that works like you want, simply because of something in the unconscious part of your mind - which surfaces when you are high.
It is still seen as a negative thing by the people around you (general population), it's illegal (you have to hide), for some unknown reason part of your unconscious mind does not like you smoking.
You have to feel like you deserve to smoke, sounds easy - but you can't lie to your own brain. It IS you, and whatever emotions that are coming out are not easily controllable.
The "regular" conscious part of the mind is like a flashlight/torch in a dark room, you are only aware of the stuff you point it at - you are in control, but when high this flashlight get much harder to control.
This is what makes people giggle, and some react differently. It IS defined as a hallucinogenic drug after all. Talking from experience (yes, it went away but took some time and effort).
