Does hair collect thc that many that it has differences between smoking the same amount of weed, lets say, clean shaved and the same amount with long hair.
And I wanted to ask something else. I smoke weed for 4-5 years now and started smoking very frequently(at least once a day) since the beginning of this summer, with few breaks. I'm starting to feel a little schizophrenik and I wondered could this be powered by the hair, I've been growing and I wonder whether I could figure out that if I shave it now, when I smoke heavily or to stop and see then. This is not a joke and I'm very serious. This could also help other people who haven't asked themselves about this.
Another thing - can a person have clear mind about that he is a scitso?
10x to all that will cooperate.
