There are generally five ways to use methamphetamine;oral, injection, insufflation
, smoking, and plugging
People generally have a preferred ROA, and it's usually their favorite either because of the bioavailability, or the ritual.
- Methamphetamine is smoked, either out of a glass bowl and stem, or off of some kind of foil. This is the most common ROA due to it's high bioavailability(~90.3%) without the risks of injection, or the discomfort of insufflation or plugging.
- Just as snorting
most other substances, This produces a quick but short lived peak followed by a few hours of coasting. Many users report the effects of insufflation last much longer than smoking . The bioavailability is a surprisingly low ~79%.
- This is a popular ROA among long time users for it's quick intense rush and the 100% bioavailability. The risks of injecting street methamphetamine are very high. A regular user is at risk of developing pulmonary embolism (PE), a blockage of the main artery of the lung or one of its branches, and commonly develop skin rashes (also known as "speed bumps") or infections at the site of injection. One also risks putting "cut" into their veins when this is done.
- This ROA is often used for it's discreet nature. Users will sometimes empty Tylenol capsules and fill them with Methamphetamine for public use. This is the safest way to ingest methamphetamine, presenting the least amount of risk factors. The only common factor being the substance itself, not taking into consideration each persons individual risk factors. Oral bioavailability of methamphetamine is ~62.7.
- This is a very uncommon ROA, due to the natural stigma of it. Using methamphetamine as a suppository involves inserting the drug
into the anal or vaginal cavity via capsule, putting the product directly into the cavity, or dissolving it in water and injecting it with a hypodermic syringe with the needle removed. Some users report increased sexual satisfaction due to this ROA. The drug will have a fairly easy onset with a high peak, a long coast and an easy comedown
. The bioavailability of suppository methamphetamine use is ~99%
The effects of methamphetamine can vary greatly from user to user when compared to other drugs
. This is mainly due to variations in how the product is produced, as well as the large range of quality from one batch to another. Different types of crystal meth, and quality of crystal meth can greatly differ from country to country, and more specifically, even city to city. Meth can also provide different effects depending on the route of administration used.
Since users of meth often stay awake for long periods of time, the effects experienced during the inital onset can be quite different than the effects experienced during the end of a methamphetamine binge. Methamphetamine can offer a wide range of effects, many of which are considered beneficial to the user, and many of which are considered to be a detriment.
Many of the effects of meth can also be caused by sleep deprivation or poor eating habits. Meth causes sleep deprivation and poor eating habits, and these would be considered direct causes of meth use. Any effects manifested from lack of sleep or poor nutrition would be considered secondary or indirect causes of meth use, though ultimately they are caused by meth.
The following is a list of effects that a typical user would consider to be beneficial. Some users however do not share the same desire when it comes to effects, therefore the following can possibly considered detriments to some users. Also, as previously mentioned, not everyone should expect to experience meth in the same way as another person. Methamphetamine may or may not provide any of the following effects.
