Really not that bad!

According to LA time’s 14 people who attended raves produced by two Los Angeles-based promoters since 2006 died from overdoses or in other drug-related incidents.  Think about it, that is 14 people since 2006 which makes about 2 people a year, and if it’s 2 promoters for raves that makes the average lower, because these two promoters throw at least two to three raves each a year. Of course most of the deaths were related to ecstasy, people take ecstasy to make their senses grow stronger, make lights seem brighter, music seem better, and give them a high to apparently have more fun. On the contrary 99% of people at raves do not use drugs and just go to enjoy music that they love with friendly people.  Despite warnings of drug risks from law enforcement and health officials, the raves staged by Rotella's firm, Insomniac Inc., and Gerami's Go Ventures Inc. have received the blessing of local governments hungry for the revenue they deliver.
