Is anything known about the interaction between various cannabis namely THC, CBD or CBN. The police constable asks because he usually smokes cannabis with tobacco infact always smokes cannabis with tobacco. He had purchased some fairly nice hash, He bought an eighth and on the first day he smoked it with tobacco and found it just made him very aswell, as stoned. Running out of tobacco he wacked it in his (now broken) glass pipe had a few hits and after five minutes e was more alert is heart was racing he felt giggly and awake, compared to drowsy sleepy and lethargic as he felt the previous day. When he smokes a pure cone of weed he finds the same thing even in more indica varieties.
