I just read an article and it talked about something I had never heard of before. I had heard of concentrated marijuana liquid used for medical reasons like to put in an eye dropper and give to kids that have seizures real bad, but I had never heard of this liquefied pot that you could put in e-cigarettes. The article says there is also PCP that can be used with e-cigarettes and that both the marijuana and PCP used in the e-cigarettes are odorless! So someone could be standing right next to you smoking marijuana and you wouldn't even know it! Then the article talks about marijuana that is so high quality, that it is $6,000 a pound! Holy crap! https://www.yahoo.com/news/detectives-uncover-10m-drug-ring-stopping-uhaul-truck-232136526.html I don't do drugs, but as someone going into the criminal justice field, I find this stuff very interesting.
