Heroin is essentially an "armored" form of morphine, protected at the blood-brain barrier by diacetyl radicals. Brain chemicals known as endophins have the same effect as morphine, but differ slightly in chemical composition.
Heroin is an illegal drug that is similar to morphine and cocaine. It certainly can cause memory loss because heroin abuse can cause brain damage. Heroin is a depressant, and causes your body and brain to slow down. If you overdose, it will stop your heart and breathing.

Heroin's biggest effect is on libido, people who take it have a reduced interest in sex. About two-thirds of women and 19 out of 20 men who take heroin regularly will find that they have reduced interest in sex. There seem to be two reasons for this.Heroin (and other drugs extracted from opium) cause an increase in the production of a hormone called prolactin. High levels of prolactin cause reduced sexual interest.Heroin seems to interfere with the parts of the brain concerned with sex drive and with orgasm. A large proportion of men who take heroin find it difficult to orgasm (come). If they take a lot of heroin they may find it impossible. Women may also find they can't come. The heroin is acting on the same brain systems which are active when we orgasm and interfering with their workings.The good news is that once you stop taking Heroin, the sex drive returns.
