You're getting good advice and bad advice.

Find yourself a local lawyer, ask for a consultation to get options (some offer free consultations) and lay out the situation. Explain what you hope to get out of it (such as money back, strip club held accountable for predatory practices) etc and how to go about it.

There are a few options that can follow. The first would possibly be the lawyer sending a letter telling them to refund the money or issues will follow. Lawyer may get DEA and cops involved - guiding you through the process to protect you from blowback.

If you have any drugs in your possession, (car, home, etc) get rid of them before the cops get involved. Do not take any drugs until this process is over. Having been on drugs is a harder crime to prosecute, if any. Were you under the influence? Sure, did you purchase drugs? Yes, but this is also after the fact. Depending on how it's approached, your lawyer can protect you.

But the first step in this is to contact a lawyer, get official, non-reddit options on the table and guidance.
