Brief Answer: Yes sir it most certainly can Detailed Answer: Hello sir and welcome. Yes sir, it is quite possible that this could be due to your drug addiction. You did not mention this in your history, and such a reaction can be either due to withdrawal or an intolerance/overdose. If you plan on withdrawing from the medication, I would advise you to take the help of a specialist (de-addiction specialist), who will help you to safely withdraw from the medication. Hope this helps sir. Best wishes.
