Street heroin is usually mixed with other things, therefore, it is hard to know how strong the heroin is. This can lead to accidental overdose or death.

Immediate effects can include

  • feel really good
  • make physical pain disappear
  • make you feel sleepy
  • feel nauseous or vomit

Effects depend on...

​What heroin does to you depends on how much you take, how often you have been using heroin (the longer you use, the more you may build up a tolerance to the effects), when you last took heroin, how pure the heroin is, your height and weight, your general health, your past experience with heroin, whether you use heroin on its own or with other drugs.

  • make your breathing become shallow
  • make you feel sleepy
