I agree a thumbprint will make you trip hard and for a long time...you need babysitters for such situation, but it won't fuck you mind up....it might change your outlook on life for quite a long time but won't set off schizophrenic episode for the rest of your life, unless you are ij fact a schizophrenic already. Also yes a gram will costs you at least 12k, i recent was gonna pick up .5 grams to lay some super high mic'd blotter for SR and my price quote was 6- 6.5k
