I have take methylphenidate, 20mg snorted and 40mg orally and I have tramadol but I think is dangerous to mix tramadol with stimulants because of the seizures risk. How dangerous can be take 100-150mg tramadol?
You are correct that it's dangerous to mix the two and to try to give a risk severity calculation on a certain amount would be irresponsible. Even if someone else has an anecdote about how they have taken X amount of Tramadol with a stimulant and lived doesn't mean you will be able to do the same. This is one of those scenarios where you should pick one or the other as trying to justify the risk is not HR.
