i'm not a spécialist , but my question is dna domage can be caused by marijuana ? the smoke cause domage it's sure , because the burnt produced monoxide carbone , goudrons etc....but what about vaporising , eating space cake ? i know the medicinal use is by oral liquid thc , or , as the consummers prefers , vaporise . what toxicity that can really have ? i don't know !but as fortuna imperatrix mondi , it's too cheap to smoke joint of marocco with parafine and a lot of good things in the same way.....
