When does meth peak?

Ways of using meth affect peak times

Methamphetamine is a highly addictive stimulant. Meth can be snorted, administered orally, or dissolved in water or alcohol and injected. Orally taken meth produces a peak in effects more slowly. Smoking or injecting meth are more popular modes of use because peak blood levels are reached in a few minutes of administration. Meth’s effects may peak quickly, but they also fade quickly, which is why people who use methamphetamine often take repeated doses.

What influences the onset of methamphetamine’s effects? What are the signs and dangers of meth addiction? We review more in the following article and invite your questions in the section at the bottom of the page. In fact, we try to provide a personal and prompt response to all legitimate enquiries.

What’s in meth?

Methamphetamine comes in several forms, including powder, crystal, rocks, and tablets. It is a powerful and highly addictive stimulant. Meth is a man-made (synthetic) drug, usually manufactured in illegal meth labs by mixing different forms of amphetamine or derivatives with other chemicals. The key compounds used to create meth are toxic and highly flammable.

These are the chemicals commonly found in methamphetamine:

  • acetone
  • anhydrous ammonia (fertilizer)
  • ether
  • hydrochloric acid
  • lithium
  • pseudoephedrine
  • red phosphorus
  • sodium hydroxide
  • sulfuric acid
  • toluene

N-methylamphetamine is the main active ingredient found in meth; ephedrine or pseudoephedrine are also common. These two ingredients can be found and extracted from many cough medications, while the other chemicals are extracted from batteries, brake cleaner, engine starter, fertilizer, rubbing alcohol…all common household supplies.

Methamphetamine peak levels

The time needed for meth effects to kick in and to reach peak blood levels depends on the mode of administration. In addition to this, peak meth levels can be influenced by the drug manufacturers, which can change the way the drug dissolves and modify its solubility characteristics.

Peak blood methamphetamine concentrations are:

detected shortly after injection
within a few minutes of smoking
within a her hours (2.6-3.6 hours) after oral administration

Methamphetamine is metabolized to amphetamine, p-OH-amphetamine and norephedrine. Peak plasma concentrations of the active metabolite amphetamine occur within 10 hours after methamphetamine use. With meth oral, the amphetamine metabolite peaks at 12 hours after initial use. While, following intravenous injection, the mean elimination half-life is about 12.2 hours.

Dangers of long term meth use

Similar to other illicit drugs, long term meth abuse and addiction can have many negative consequences on health, including functional and molecular changes in the brain. Here is a list of possible risks and dangers caused by prolonged and chronic meth abuse:

  • addiction
  • aggression and violent behavior
  • damages in the brain structure and function
  • dental problems
  • difficulties in thinking and motor skills
  • hallucinations
  • increased destructibility
  • memory loss
  • mood disturbances
  • paranoia
  • psychosis
  • weight loss

How do I know if I’m addicted to meth?

This article is very informative.

Meth indeed has long term health hazards if meth abuse is done over a long period. It would really be helpful if effects of meth would be discussed in more details to give more insight.

How long does it take for meth to get out of your system so i will pass urine drug screen. Smoked approx 3 months almost at a gram per day.

Hi Donna. Meth can stay in the system and be detected in urinalysis drug tests 1-4 days after use. But chronic use can extended this detection period.

I am rather surprised to see that Methamphetamine is not listed as one of the chemicals of what is in Methamphetamine. I understand pure drugs are rare but I would expect at least some methamphetamine to be in methamphetamine. Further, aren’t many of the aforementioned chemicals also used in the synthesis of a multitude of both over-the-counter and prescription drugs. For example hydrochloric acid does indeed sound scary and I would never put that in my baby’s bottle, however, Methylphenidate the #16 most prescribed pediatric medication also contains hydrochloric acid (any drug that has the form drugname.HCl does). I would also hazard to guess that sodium hydroxide is used in the manufacture of this child’s medicine, it’s actually contained in my current toothpaste.

Interestingly enough methylphenidate has very similar effects and side effects as methamphetamine. One we vilify the manufacturers and customers of the compound,whereas the other is freely give to kids as young as 6, as stated in literature.

This site considered the links to my sources as “spammy” therefore I had to remove them.
