When you call, we ask for the information above. After we’ve received the info, you can go ahead and use the substance. We then stay on the phone with you while you use your substance. We ask you to let us know when you’re done, so that we can start watching the clock. We will then continue talking with you for a few minutes (usually about 10 min minimum) to be sure you’re going to be okay. If you stop responding for more than 30 – 45 seconds, we then contact EMS.
