The "contact high" myth is not true. The buzz that people feel when they claim they are getting a contact high is actually the available oxygen supply in a small space, lets say your buddy's VW Jetta, being replaced with smoke. They are feeling a buzz from lack of oxygen to the brain. You will not get a contact high, it is chemically impossible. The smoke from the materials being smoked, and the smoke exhaled do not contain enough tetrahydrocannabinol to produce even the slightest effects on your system.
You inhale to much.
Honestly, it really depends on how much of the smoke you inhale and how often. If you hot box with your friends on a daily basis and experience a "contact high" I would definitely be worried. And I am sure trace amounts will show up even if you have only done it a few times, getting a contact is still getting high.
Depends on how much contact you had with it!
This does not physically get you high, but works by decreasing oxygen to your brain, which makes you feel high. If you inhale too much you can die as the lack of oxygen kills brain cells
You can not get "High" from CO2. What happens when you inhale CO2 is pretty much your brain shutting down from oxygen being replaced by carbon dioxide. Your body stops functioning to the point of unconsciousness, if you inhale pure CO2 you can die and/or go into a coma after several minutes.
Smokers inhale 15% and the 85% Non-Smokers inhale
20.9%
not long depend on what it is and how much you inhale but not long though
it depends on how you inhale
Why don't you use a mask? When working in such conditions I would say health first. There are many masks on the market that can filter even the tiniest particles out of the air that you inhale. There is a very big risk if you are inhaling too much dirt.
if you inhale it to much it can give you a infection
When you inhale helium it raises the pith of someones voice. But, if you inhale it to much or to often it can result in asphyxiation due to oxygen deprivation.
