I've smoked tar plenty of times, but this one time was the oddest. First hit of the day and i immediately started getting SHARP pains in my chest, like getting stabbed in the heart. It didn't go away for 30 minutes at least and i didn't feel high at all. I've been doing H for 2 years now only smoking and I'm so confused why i felt like this. Was i started to OD? Helpppppppp i want insight!!
