Hi,
3 months ago I did a drug known as NBNOME-25I. It is a research chemical. I did this drug 8-12 times. It is known to cause vasoconstriction. The last time I did it I started to feel very ill. I was having extreme pains in my sides and chest. Since then I have had chest pains in the left side of my chest, directly where my heart is located. I went to the er 5 days after the last time I used, and I had an ekg come out normal aswell as my blood pressure appearing normal. The pain varies from a choking pain, to sharp pain, and just a terrible feeling in general. It will radiate up to my neck. It becomes unbearable if I smoke weed, and is unaffected by smoking cigarettes. This drug is similar to methanphetamine.
