But illicit drugs like heroin often lead to complicated health problems. In its pure form, heroin is relatively non-toxic to the body, causing little damage to body tissue and other organs. However, it is highly addictive and regular users are very likely to become dependent on it, even after a few days. Some long-term effects include constipation, menstrual irregularity and infertility in women and loss of sex drive in men. Users often spend less on other things like housing and food and, combined with reduced appetite, this can lead to malnutrition and susceptibility to infections.
Additives can be very poisonous.
They can cause collapsed veins, tetanus, abscesses and damage to the heart, lungs, liver and brain. Because the users don't know the purity and as a consequence the amount to take, it is easy to accidentally overdose and even die. HIV is also transmitted through unsafe vaginal and anal sex. The correct use of a condom can prevent infection. Tolerance and dependence Tolerance People who are physically dependent on heroin usually develop tolerance to the drug, making it necessary to take more and more to get the desired effects.
