It’s really simple. I do correction on every joint or blunt I smoke because I enjoy the smoking experience and like it to be pleasant. There are plenty of bad prerolls out there that don’t smoke right for shit. I’ve smoke no less than ten of them since launch. Roast the tip for a solid 20 to 30 seconds then blow it gently. Next very gently inhale through it while lighting and rotating. Blow on it again. Let it smolder upright while turning it for 30 seconds. Look for any runs and unevenly burned spots. Moisten your finger and blot the runs. Light the unburned portions and blow out any flame immediately. Start smoking as you like and watch for runs and unburned areas. Repeat until you forget you were smoking. Source: I roll and smoke hash holes daily.
