Hello, I understand your concern. Weed is known to speed the heart rate and to increase blood pressure. It can also cause very low blood pressure which manifests with dizziness or head rush upon standing up leading to fainting. Meth, on the other hand, is known to have strong effects on the heart and blood vessels, by increasing the heart rate (tachycardia), narrowing the blood vessels, raising the blood pressure, and thus, putting additional strain on the heart. Now, if you combine weed and meth together, it goes without say that the strain on the heart is doubled or even tripled. A strained heart can barely do its job properly to deliver oxygen and nutrients to the body, thus depriving the body cells, among which also the nerve cells (hence the numbness). These effects are even worse when the quality of the drugs you take is compromised with other chemicals. Bottom line, you had a close call. Next time could be fatal. Please take care of yourself. You only get to have one body and it will have to serve you for the rest of your life. Wishing you good health and all the best.
