I could be a little wrong here.....but my buddy works in Cali installing sunlights on homes and has a script out there.....he brought back 3 grams of pure THC extract in little medical looking vials.....it was honestly the strongest stuff Ive ever smoked in my life.....no bullshit 1 hit had me very stoned for about 5 hours......I do believe Hash extracts are fine in Cali...but I could be wrong.
