I've heard drug withdrawal can cause seizures in some people, after that person has gone through withdrawal and no longer has the urge for a drug could it be possible seizures would stop?

Far too little information. I take it this is the close friend of your ex girlfriend, who your ex would rather spend time with. Please, try to leave it alone. You are grasping at straws to keep this relationship going.

Yes it's my girlfriend and our recent issues have been solved the friend of hers isn't involved since the nurses had to step in because she was effecting her health, gfs parents fully support me and her together. After 3 days in mental hospital she had a seizure and everyday since they go for about 30 to 45 minutes looks like she is sleeping but all tense and will gasp for breath every now and then, my question was if she had been taking drugs from her girlfriend or even on her own behalf could the withdrawals causes seizures and once withdrawal period is over could it be possible they stop?

Your girlfriend is the one having the seizures? And you think she is in withdrawal, or overdosed on some psychiatric drugs? Are you just guessing?
No one online can possibly answer this.
What you describe (go for about 30 to 45 minutes looks like she is sleeping but all tense and will gasp for breath every now n then) doesn't sound quite like any seizure I know of. Is this when you are visiting? Who is telling you if not? She may just be withdrawn.

They could stop, but then the drugs could have done chronic damage to her nervous system. Now more medicating to withhold the seizures may not work and she will be stuck with permanent damage. Now she faces a life of 'what ifs'

I never asked for you to solve it rather tell me if drug withdrawal can lead to seizures and after the withdrawal period could things return to normal it's not like I'm going to run around saying I have found the reason it's more so I can cancel it out if that's a possibility

There is no concrete answer for a hypothetical question such as this.
