Ah okay

TDS deals more with the psychological aspects where as we deal with safety issues, combination questions, dosing queries etc.
There is a drug interaction checker
here (and more can be found using google) - it found no interaction with amphetamines, and a moderate interaction with ketamine (see
here). It doesn't incluce cocaine or tryptamines.
One thing to bear in mind is that taking drugs which affect your neurotransmitters and play with your general brain chemistry isn't always the best plan if you have mental health problems.. stimulant crashes can be pretty intense, and there is a risk of stimulant-induced psychosis as well. Mind-altering drugs such as dissociatives and tryptamines, while potentially having a positive impact, can also have a negative one and I would be cautious if I were you. I know of someone who greatly exacerbated mental health problems by using a lot of ketamine, and someone else who greatly exacerbated a psychotic episode with a bad psychedelic trip. Not to say that they can't be beneficial, but tread carefully
