Hello, This is Dr. Viraj Shah, Master of Public Health answering your query. It would have been helpful if you had mentioned if you are a regular user of Meth and having addiction to it or it was your first experience of using Meth while you experienced the episode you described. I will explain you for both scenarios. In case of the first time use, it might be possible that you experienced sudden increase in blood pressure and tremors etc. as a natural response of the body to the harmful substance to the system. It can be considered as a body s way to give you a message that your system is not ready to accept such addiction. If you are feeling fine right now or improving, then you can wait till the body processes the substance and gets rid of it from the system to feel better. However, if your condition worsens, you should visit an Emergency Room for the treatment of the poisoning with Meth. If you are a regular user, it might be a sign of worsening neuronal conditions in your body and might lead to stroke in future. It is time you quit using the drug and restore better health. However, it is advisable to visit a physician or neurologist regarding the experience to find out if a damage is incurring to the nervous and cardiac system. I hope this information helps you. Thank you for choosing HCM. I wish you feel better soon and decide to quit using or experimenting with the drug.
