I am old enough that I should have known better. I am a many decades pot smoker. I don’t drink, smoke cigarettes or use any other drug. I know pot pretty well and it agrees with me. My niece came to stay with me this weekend and last night she asked if I wanted to smoke. She knows I smoke. She did not tell me it was not normal pot when she pulled out a joint. I smoked and by the 4th or 5th pass my heart started pounding and I had to excuse myself to go to the bathroom because I thought I was going to throw up. Once in there things got really scary and I thought I was dying and having a heart attack. It was terrifying and it was combined with the most horrible empty depression feeling I have ever experienced in my life. I could kill her for not telling me. Since then I have had 2 similar panic attacks but not as strong. Is there anything I can do know to get this out of my body faster and make the panic go away?
I suggest you see a doctor to address the panic and other symptoms you are experience if they continue. I would prefer a psychiatrist who is also an addiction specialist since he/she would best understand the determinants and appropriate meds if necessary. You might want to see if the situation abates in a few more days since you mention that it is subsiding.
As for you niece, I would see what was in the pot, if anything. It is a serious matter when someone introduces a chemical into another without telling him/her. It is extremely dangerous as you experienced, if this was the case. I certainly would talk to her in very strong terms. If you had a heart problem, it could be fatal and she should be made aware of the many dangers.
