What do Inhalants look like, and what are the side effects?

For project!

Inhalants come in a variety of forms. I assume you are asking about inhalants that cause intoxication.
One inhalant, amyl nitrate, is usually in a fragile glass vial that can be easily broken. This is generaly used by people suffering from heart pain due to a sudden drop in the amount of blood getting to the heart. Amyl nitrate is a powerful heart stimulant that has saved many people's lives.
But some people use it at the moment of orgasm to heighten the pleasure. If you have a weak heart, or high blood pressure,this is a really bad idea as it can cause sudden death or a stroke.
Other inhalants, such as spray paint and model airplane cement, are also very dangerous. Spray paint is hell on the lungs, kidneys, liver and brain. Toulol or tolulene, the active ingredient in many brands of model airplane cement, is an industrial solvent that is also hell on the kidneys, liver and brain. This chemical as well can cause sudden death in the absence of sufficient ventilation; otherwise it causes stupor, hallucinations and bizarre behavior. It can probably cause lesions on the brain and tumors as well.
Carbon tetrachloride (spot remover for laundry) is another very powerful industrial solvent; this **** can kill you really fast. The only safe inhalants are medical inhalants (like those used for asthma), and even with those some people have fatal allergic reactions. If you want some good advice, don't use inhalants!

Inhalants??? Look Like??? I suppose you mean the 'dispenser.' An inhalant is a "gas" or air born chemical. For medical purposes comes in a dispenser that either sprays or fumes into nose. Then, there are "recreational inhalants...glue (very bad idea), gasoline (even worse idea)...anything that gets you high...usually at expense of oxygen.

Many inhalants used to get high are colorless. All of them have severe effects on the pulmonary and cardiovascular systems and can cause permanent disability or DEATH.

Well just about any spray paint, and some solvents are used as inhalants. The side effects are brain, and Neron damage, and the early onset of senility.I would recommend talking to your doctor, or some local health care professional before trying any of these substances.If you truly feel the need to alter your state of consciousness,Why not try exercises? It raises your level of endorphins,and that helps promote euphoria.I have seen the result of allot of folks who got hooked on huffing paint, and believe me, it isn't pretty!!
