Though heroin and cannabis are two of oldest drugs, they still hold their own stead in the presence of newer drugs like LSD, cocaine and meth. Heroin has been legally used even as early as the 1800s. Today it is used majorly as a recreational drug due to the intense euphoria that it creates in the mind of the user.

Heroin can also be mixed with cocaine to create a speedball. It is normally injected intravenously, smoked, or dissolved in water and then smoked. This is known to have a more intense rush as compared to only cocaine or heroin, but it is also more dangerous, because the slow acting stimulant and the longer acting depressant are used together, which may create a overdose of any of the two drugs. Heroin is a potentially dangerous drug addiction, and the long time repercussions of heroin may be damning to the personal and professional life of individuals. Fatal overdoses, collapsed veins and other serious health conditions are just the beginning. Users who inject the drug may have such infectious diseases like HIV/AIDs and hepatitis.

Heroin itself has short term and long term effects. After the surge of euphoria, which is accompanied with a warm flushing of the skin, along with a dry mouth, the user also has an alternately wakeful and drowsy state. The mental functioning of the individual becomes clouded due to the problems in the central nervous system caused by heroin. Therefore, heroin rehabilitation is extremely necessary, and that too as soon as possible.
