am I immune to ecstasy?

[SwallowTheSun]

ÉA couple of months ago swim got these blue XTC pills (dont ask whet kind they were) and the guy swim bought them from said they were pretty good but take longer than usual to start to work. swim and friend said they would start off with 1 each and so did at around 11:30-12:00. 2 came around and swim's buddy said he was having a pretty good time and swim didnt feel no different, so swim thot they would take another pill, 3:30 came by and still nothing so swim had a 3rd one. they stayed up till 7 but swim never felt a thing. And yesterday swim had a pill at around 8:00 at night, and i know E is suposed to make you somewhat hyper, and swim only got trieder from then on in with absolutly no effects. Today swim parachuted half a pill (the same kind as yesterday) and nothing. bare minimum swim was a little talkative but i would even say it was a suger rush.
i know swim is taking them right cause swim's friend whos exprienced showed them.
no-one can explain why this is happening to swim.
why is this.
