hello guys
i have 3 pots of lophophera williamsi cactus i wonder if any one know that these have enough mescalin or not ?
i heard that just one race of lophophera williamsi have enough mescalin to trip with is that true?
and another thing that i heard that these must flowering then we can use it is this true?

thanks

Those are some nice looking cacti. (Someone correct me if I'm wrong) if those are L. Williamsii that is traditional peyote, so yes, it contains enough alkaloids to have an experience from.

I couldn't tell you if they are ready to be harvested though

thanks for your answer
