I have run into that problem myself. The only solution I have found is to take breaks from the oil. Then my body's THC tolerance returns to normal. I usually take a 4 day break from it. During that time, I usually feel pretty lousy, no appetite, short-tempered and grumpy.

I would say a prescription approach that might work is to administer cannabis oil for 3 weeks and then do a week of something like trazadone to decrease tolerance and switch back after that week. But I am not a doctor, so who knows.

So I can't say totally that I believe it isn't a little addictive. But I was addicted to cigarettes before and can say it isn't like that, it's more of a mental crutch or outlet that helps me reframe my thoughts and relax.

Although, sometimes I work so much that I just naturally have these t-breaks because I have to work late and go in early again and don't bother with edibles.
