Drugs are taken in various ways, such as:
By inhalation (breathing in) (volatile substances, ether);
By smoking (tobacco, hashish, opium);
By swallowing (alcohol, etc);
By mixed routes from the mouth:
The intravenous route is the most sought after because it provides the additional effect, the so-called "flash". The product in direct contact with the blood, which circulates in the brain, creates a state of pleasure, explosive desire, up to orgasm, lasting a few seconds, and then continues with the impression that the addict is in a world without worries. From the standpoint of libido, there is an extremely primitive autoerotic pleasure present.
