The liver is the organ that processes most recreational drugs.
Some are more toxic than others, but all will stress your liver to some extent.
Street drugs are also likely to contain impurities and other ingredients that can be toxic. In general, injecting drugs is more dangerous than snorting or swallowing them, because injecting goes directly into the bloodstream, bypasses the filtering system of the stomach.
If you are injecting drugs, using sterile equipment (syringe, cooker, filter, water, tie and measuring syringe) will protect you from HCV and other infections.
You may want to consider reducing your intake of recreational drugs, or stopping. If so, there are places where you can get help.
Some recreational drugs may have interactions with HIV drugs.
