YES, Yes indeedy.
I was sold vitamin B tablets as ecstacy. Spent $175 Aus. on them. This was from a supposed "friend", who afterwards dodged my phone-calls and refused to answer messages. Needless to say he's not a friend anymore.
Another guy I know was sold ICING SUGAR as cocaine. Again, a "friend" did it.
I honestly don't get why people would fuck up friendships for a quick buck. I wouldn't even sell fake drugs to strangers. For example, those vitamin pills... I thought for 2 seconds of getting my money back by selling them at a rave... I couldn't do it. People like that should be castrated.
GRRRRRRRRRRRRR.
