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.
