Methamphetamine is a dangerous substance that some people mix with drugs like Viagra, which can quickly lead to a variety of health and safety risks.

Article at a Glance:

  • Meth and Viagra are often mixed to enhance sexual pleasure.
  • Meth can cause erectile dysfunction and many other side effects.
  • The risks of mixing meth and Viagra include an increased rate of sexually transmitted diseases like HIV.

Meth is a dangerous drug on its own, but when it’s combined with other substances, the potential risks increase. Research shows that polysubstance use involving meth can lead to unsafe behaviors among people who are at high risk for sexually transmitted diseases.

The Use of Crystal Meth and Viagra

Polysubstance use involving meth is common among some partygoers. When these people are at nightclubs or raves, they may combine a variety of different drugs, including meth.  In particular, men may combine meth with prescription medications that help with sexual performance, such as Viagra or Cialis. Meth can cause erectile dysfunction since it constricts blood vessels, so some men use these medications in an attempt to prevent it.

The Why

Studies have shown that people mix meth with drugs like sildenafil (Viagra), MDMA (ecstasy) or nitrite (poppers) for several reasons, including:

  • Enhanced sexual experiences
  • Avoiding unpleasant emotions
  • Avoiding physical discomfort
  • Social pressure

The Risks

Meth is a highly addictive drug that can cause life-threatening side effects. Meth-related overdoses nearly tripled from 2015 to 2019, making it a growing concern in the United States.

Viagra is considered non-addictive, but it should only be taken by prescription due to dangerous drug interactions with substances like nitrates, nitrites (like poppers) and riociguat.

Combining meth and Viagra carries additional risks, including:


Is Viagra safe?

Viagra is generally safe, but it should not be combined with certain other substances due to the risk of dangerously low blood pressure. These substances include nitrites (like poppers), nitrates (like nitroglycerin) or riociguat.

Can you overdose on Viagra?

Although rare, Viagra overdoses have been reported and can be fatal in some cases. It is important to take Viagra only as prescribed and tell your doctor about other medications you are taking.

What are poppers for sex? Are poppers safe?

Poppers are liquid nitrites, a chemical that some people believe can enhance sex. However, they can be dangerous and can lead to breathing problems, extremely low blood pressure and even death. The FDA has warned against using poppers.

Does meth cause erectile dysfunction?

Yes. Doctors think meth may cause erectile dysfunction because it constricts blood vessels. Since blood flow is needed for an erection, meth can interfere with this process.
