Hi
Welcome to the forum!
Ecstasy can cause nerve stimulation followed by low sensory output and thus prolonged use can damage the nerves including the nerves involved in ejaculation and erection.
Marijuana is known to cause erectile dysfunction on long term use. Combined effect of Ecstacy and marijuana can be more harmful.
The side effects are reversible depending on how long you have used the drugs and the extent of damage. You should stop taking the drugs, probably join a de-addiction center and discuss your problems.
If you took the drugs just that day, then it was the effect of the drugs that caused erectile dysfunction. Once the effect wears off, the problem should not recur.
However confirmed diagnosis cannot be given on net. Please discuss this with an internal medicine or narcotics specialist. Hope this helps. Take care!
