It looks like it can be dangerous for some people. My friend just told me his friend's brother died with it in his system. Looking at the Wikipedia article it seems there's some health effects that can be dangerous, similar to opioids.

Sorry about your friends friend's brother. Perhaps it's not meant to be mixed with alcohol or other drugs. Not sure. 
  
 My understanding of it is that it works so well you can become addicted to it, in that not having it after a while might give you withdrawals.
