I was on risperidone for 2 years or so, then went cold turkey. (Not recommended)
I was prescribed it for Tourette’s Syndrome oddly enough..
It does affect how you get high or even drunk, but I did notice after a couple months being off it, everything went back to normal.
I can smoke and get super baked if I try now. It takes time, but it will come back, try a tolerance break from cannabis maybe (when the withdrawal of the drug eases up, no sense stressing yourself. It can cause irritability or insomnia, and the cannabis in the mean time will help take the edge off, even if you’re not “baked”)
