You can trip even whilst they're still in your system, so that isn't a problem. The only thing about combining the two is that benzos will dull the deeper and more interesting/rewarding aspects of a trip.
How long have you been on benzos, and have you quit them cold-turkey before? If you know what you are doing, then just stop taking them and you should be fine to trip within the next couple of days. But I think you should give it a few days off just to see how you are reacting in withdrawal.
I tripped on 2C-T-2 whilst in the midst of a
delirium tremens episode 3 into quitting diazepam cold-turkey (a long-term and high dose habit). The results were fucking devastating to say the very very least. Needless to say, it was a kind of personal hell that I never want to repeat.
Nevertheless, that experienced was a huge turning point in my life to start doing things better and stop being such a selfish cretin. Although I relapsed on the benzos afterwards, the door was already cracked open and I couldn't lie to myself any longer and I had to give them up a couple of months later.
I also just want to add this off-topic: if you are at the stage where you can still stop benzos without feeling major withdrawals...
DO IT, AND DO IT NOW. If you choose to keep taking them daily because you believe you are one of those people who "doesn't get withdrawals", you will fucking rue the fact you didn't take this advice. Coming off of benzodiazepines has to be one of the worst drug withdawals a human can endure, and it is
hell. They last for ages (a year or more), and it takes incredible willpower and endurance not to cave in.
On the bright side, there
is a point at which you finally emerge from this hell, and you can indeed be free of benzos. You don't have to be enslaved to them. Believe this, because I was one of the worst addicts where I felt utterly powerless to let go, and I never believed the people who said you could be happy without them. But I proved to myself and many other people that you
can overcome it. You will come out of it a much stronger, happier, and more peaceful person than you went in, which is one of the ironies of drug addiction.
