dMethamphetamine, commonly known as meth, is a Schedule II, stimulant drug used clinically to treat conditions like obesity, ADHD, and narcolepsy.

In addition to clinical use, meth is also used recreationally, which is illegal. Recreational meth use is dangerous and can lead to a multitude of health problems.

Much like many other illegal drugs, meth can be identified by distinguishable traits like its appearance, taste, and smell. In fact, the smell of meth can even help identify meth labs.

The Smell Of Methamphetamine

There are a variety of smells that are associated with methamphetamine.

Rotten Eggs

One common smell people notice with meth is rotten eggs. This is most likely due to the use of sulfuric acid to make methamphetamine.

Cat Urine

Another unpleasant and strong smell people often come across when around meth or meth production is cat urine.

Anhydrous ammonia is another common ingredient in meth, which can mimic the smell of urine.

Nail Polish Remover

It’s no surprise that some people smell nail polish remover when they smell meth. This is because nail polish remover itself is sometimes used to make the drug.

Paint thinner is also used frequently, as it contains the same ingredient, acetone.

Sweet Smell

Though many of the other smells associated with meth are quite unpleasant, it can also give off a sweet smell. When meth is smoked, it can smell slightly sweet.

What Does A Meth Lab Smell Like?

The scent of meth can actually be helpful in identifying a meth lab. This is because the production and ingredients of the drug can give off strong smells.

The most common scents associated with meth labs are cat urine, rotten eggs, and a hospital-like or chemical smell.

Other ways to identify a meth lab include visual signs such as meth ingredients and production tools.

Methamphetamine production involves the use of many tools, which may include coffee filters, rubber gloves, glass containers, and more.

If you ever do happen to come across what you suspect is a meth lab or meth house, be sure to leave the area to keep yourself safe and notify law enforcement immediately.

Factors That Contribute To The Smell Of Meth

If you’re wondering why the smell of meth can vary so much, there are a few factors this can be attributed to.

Factors that can contribute to the smell of meth include the formula, ingredients, and cutting agents or additives.


The formula of methamphetamine is quite specific when used clinically. However, when meth is made in labs or at home, the formula involves several chemical reactions.

Specifically, many people use pseudoephedrine, the ingredient found in many over-the-counter cold medicines, to make meth.

These chemical reactions can give off strong scents, causing particular smells.


The ingredients of meth can also contribute quite heavily to the smell of meth. The ingredients can vary greatly, which can explain why the smell may be different between batches.

Common meth ingredients may include:

  • cold medications
  • ephedrine
  • paint thinner
  • nail polish remover
  • alcohol
  • fertilizer
  • lithium battery acid
  • iodine
  • hydrochloric acid
  • hydrogen peroxide
  • drain cleaner
  • starting fluid
  • cleaning products
  • chlorine
  • red phosphorous

Of course, this is not an exhaustive list of meth ingredients, but rather a list of the most common ones.

Due to their own scents as well as the reactions that occur when they’re mixed together, they can create unique and powerful scents that differ between batches.

Cutting Agents And Additives

Lastly, cutting agents and additives can contribute to meth’s smell. Cutting agents can include ingredients like milk, talc, and sugar, which may explain the sweet smell crystal meth gives off when smoked.

On the other hand, additives like amphetamines, opioids, and fentanyl can also alter the smell of methamphetamine.
