Makes you feel like shit for the whole night;

Makes you pray to god that you'll never smoke weed again,

Makes you say sorry to the person taking care of you, because you know in your head you just sobered them up & ruined their night,

Makes you feel like you're falling into quick sand, and your hand movements seem amaizing.

Makes you question if you've fried your brain, and this will never go away, and you'll live like a vegetable for the rest of your life.

After smoking (normally Marajuana) you may experience greening out.

Greening out basically is when you smoke and get really sick. Normally it comes with dizziness, impaired vision and balance, passing out, nausea, or in some extreme cases vomiting. You may also become sober extremely quick. Sometimes you may also experience chills and cold sweats. Normally, in most cases, it happens with non-smokers who are doing it for the first time.
Person 1: "Man I just took a fat ass dab and now I feel sick."
Person 2: "Bro your greening out, fuck!"

A green out is a cannabis induced physiological or psychological panic attack. Symptoms include sweating, nausea, heart palpitations, hypervigilance, paranoia, and the fear or feeling that you might be dying or about to die. A green out is typically caused by smoking or ingesting too much cannabis too quickly.

Green outs are generally brief experiences and may be followed by exhaustion or drowsiness, or a rapid sobering.

Unlike black outs, memory loss doesn't tend to occur during a green out due to the intensity of a green out.

Memory loss is much more likely to occur during a long, sustained session of cannabis use.

Unlike alcohol, cannabis use affects short term memory (what was I saying?) and not long term memory (what did I do last night?).

Sativa strains may be more likely to cause green outs (while indicas are more likely to leave you stoned)
Person 1: Dude, don't smoke so much. you'll green out.
Person 2: pshh, green out, sure, whatever.
(green outs vary depending on the circumstances so it's difficult to describe a specific example, and it can take multiple green outs to really understand what's happening when you have one).
Person 2, now an experienced pothead: Dude, don't smoke so much. you'll green out.
Person 3: pshh, green out, sure, whatever.

Involves constant throwing up and feeling extreme nausea and dizzyness for the rest of the night, possibly with continued vomiting later on. In more extreme cases, the person in question may experience hallucinations.

Occurs when someone smokes a lot of marijuana in a short period of time. Common amongst those who want to prove their masculinity somehow by smoking large amounts, usually through peer pressure.

Usually ruins the night for everyone else, as it means they must look after them and take them home. So people who green out often aren't very popular with the rest of the dope heads.
Person 1 : "Wheres he going? Oh no, he's greening out."
Person 2 : "For fucks sake, not again."
