The most harmful physical consequences associated with heroin addiction depend on how it is taken, the impurities found within the drug and the addict's living conditions. The most serious effects are usually the result of intravenous use and the use of dirty needles and syringes (skin infections, tetanus, hepatitis, HIV/AIDS, etc.).

Tolerance (need to increase the dose to feel the same effect)

Develops quickly. Users can increase their dose 100-fold from the initial dose.

Addiction

Yes (physical and psychological). It can develop very quickly, within a few weeks in most cases. The risk of addiction increases when the drug is injected.

Withdrawal

Heroin addicts may become so preoccupied by the powerful need to get heroin to prevent withdrawal that it takes over their daily life. Withdrawal symptoms usually begin within 6 to 12 hours after the last use (muscle aches, malaise, watering eyes, runny nose, fever, sneezing, chills, shivering, tremors, excessive sweating, anxiety, agitated sleep). Symptoms reach their peak over the next 36 to 72 hours (abdominal pain, vomiting, diarrhea, mydriasis (dilation of the pupils), intense drug cravings, aggression, rage, paranoid delusions, tachycardia (increased heart rate), hypertension). Most symptoms subside after about 5 to 10 days.
