Is it possible smoking crystal can create worms in your head?

It's hallucinations!: Smoking crystal meth, methamphetamine, is a dangerous and highly addictive habit. It causes poor dentition, weight loss, brain damage, and other physical and mental problems. It frequently causes socioeconomic problems too. The "worms" you are feeling in your head probably is a result of having hallucinations or brain injury from smoking crystal meth. I strongly encourage you to go into Rehab now!

No, but it can...: To get worms that travel to the brain one must ingest the eggs of those worms. In the unlikely event that crystal meth contained worm eggs I would expect the heat of smoking it would kill them. But crystal meth can create delusions and hallucinations that make you feel like you have worms in your head. However, crystal meth has MUCH more serious hazards than worms.
