Can't stop thinking about meth.

I have been clean for 5 weeks after blowing through around 10k in 6 months, using multiple grams per day. The first few weeks were easy and now I can't get it off my mind. I really want to try psychedelics as a spiritual approach, preferably mushrooms and I think 90% of the acid around here is nbomes and people are too stupid to know the difference. What would you suggest?
