Cigarette Dipped in formaldehyde?

[louiset]

My fiance's sisters boyfriend "disapered" from 2pm friday afternoon until 7pm this evening. Last she heard from him he was going over to a girls house, then never called or gave any indication were he was. The other thing is this guy is that he is a chronic liar. He tells some of the dumbest stories to make his life seem so amazing.

This evening he came home and said he had been out all night and didn't call because his friend dipped a cigarette in formaldehyde and he didn't know about it. He said that he was so out of it that he couldn't make a phone call for the past 24 hours.

My fiance's mom says he is talking like his jaws are clenched and his eyes are a little bit red and moves like it hurts.

Could his actions be fake? Could this drug have effects on him 24 hours later? If he did smoke it, would that cause him to have the inability to pick up a phone and call?

Any help is great. thankyou
