I've tried all 3 ecstasy , coke and speed - speed is the 'poor mans coke' - you get an awful comedown off it and you hardly ever get decent coke, the best is E - the effects of both drugs combined AND an really intense(but controllable) euphoria AND its so much cheaper than the other 2 - well it is in the UK anyway - I've tried coke and speed a few times but cant see what all the fuss is about, but Ecstasy is a different story - it does exactly what is says on the tin
