How long after taking stimulants do they affect ecstasy?

My buddy recently took 240mg of Vyvanse so he could drive all night long to get his car over to his new house. He probably took it 36 hours ago and we were planning on rolling tonight. Is it dangerous for him to roll because of the vyvanse?

I have looked everywhere and have not seen an answer to this.

I don't see any danger at all but since Vyvanse is and amp, the cross tolerance could effect the intensity a bit. Other than that I don't see a problem...people take Adderal and other ADHD meds before,during , and affter MDMA use and have no issues so i would suspect that same with Vyvanse.
