The smell of smoke mixed with the aroma of marijuana still wafted through the southwest Calgary neighbourhood yesterday, hours after the $250,000 fire at the home at 2616 24 St. Neighbours were startled by a loud noise about 9:20 p.m. Monday. "It was a very loud boom -- it sounded like something fell from the sky and hit the roof," said Connie Loveday, who lives with a roommate next door to the dope house. At least one man had been inside the three-bedroom bungalow trying to cook the pot to condense the THC, the active ingredient in marijuana, from the weed. "What the (drug cookers) do is soak the (marijuana) leaf and buds in isolpropyl alcohol to leech the THC out of the plant," said Sgt. Roger Morrison of the drug unit. The tricky part is when the weed is taken out of the mix, the alcohol must also be removed and the quickest way to do that is to heat the mixture. The ensuing vapours are so strong, a spark can cause an explosion, and that's what police believe happened.
