<human>:  I think my neighbor may have a drug problem. What should I do?
<bot>: Ideally, you should try to confront them and see what their response is. If they seem to confirm that they have a problem and are willing to get help, it may be beneficial to call a local or national helpline for further advice or to see if there are any resources available in your area to assist your neighbor. Ultimately, the best advice is to trust your gut and take action if your instincts are telling you that something is wrong.
