It is really wrong to abuse any class of drug be it opioids, narcotics, NSAIDS, steroids, antibiotics etc.
If you have got a headache it is easy to get paracetamol because your aware it is an analgesic but now some persons just buy it and take an overdose unknowingly without asking for the appropriate dosage.
It is important we all stay away from abusing drugs.
The side effects and adverse effects from this might be a long one.
