Can You Smoke Marijuana While Taking Nyquil?

As with many common over the counter medicines, they have to potential to interact with marijuana in unexpected ways if you aren’t prepared. While it is always recommended to avoid mixing different drugs if you are unsure about the side effects, you may find yourself in this predicament as a regular cannabis user who requires the treatment of cold medicine.

We’ll break down the various uses and side effects of Nyquil, as well as how it will interact with marijuana if you take both drugs simultaneously.

The Uses and Side Effects of NyQuil

An over the counter cold medicine, Vicks NyQuil is a common household drug that is used as a decongestant, cough suppressant, and general breathing aid. It is a relatively safe treatment for the common cold and flu symptoms, acting as a fix-all medicine for minor illnesses.

The main effective ingredients found in Nyquil are as follows:

  • Dextromethorphan
  • Acetaminophen
  • Doxylamine

The main active ingredient that suppresses many of the flu-like symptoms is dextromethorphan, acting to alleviate the coughing often associated with colds and flus. The second main ingredient acetaminophen, commonly known as the brand name Tylenol, is a pain reliever and acts to reduce fevers.

The last key ingredient in NyQuil is Doxylamine, an antihistamine that helps to treat congestion, sore throat, and sneezing. Doxylamine also acts as the sleeping aid ingredient in NyQuil, being replaced by Phenylephrine in the day-time equivalent DayQuil.

Side Effects Of NyQuil

While NyQuil does have the potential for addiction or abuse, for the most part, the average consumer will run into minimal issues taking this over the counter medicine. There are, however, some minor side effects that you may run into.

They are as follows:

  • Drowsiness
  • Dry mouth, throat, or nose
  • Nausea or vomiting
  • Stomach discomfort
  • Blurred vision
  • Dizziness
  • Lightheaded feeling

Because both cannabis and NyQuil are fairly subtle drugs, both with minimal side effects, the risk of a severe drug interaction is minimal and shouldn’t be a cause for concern. However, there are some amplifying effects when combining the two, especially when it comes to the drowsiness you will feel with both drugs.

The sleeping aid in NyQuil, Doxylamine, is a pivotal ingredient while sick with flu-like symptoms. If you have ever taken NyQuil over the counter, or a similar product, you can attest to the strength it carries in allowing you to fall asleep where you would normally be kept awake with an agitating cough or other symptoms.

Many types of cannabis also result in drowsiness, especially with strong Indica strains. Because both carry these effects, you should be wary of combining the two unless you anticipate sleeping relatively soon after intake.

Anecdotally some have reported that NyQuil may also amplify the ‘high’ feeling associated with cannabis, however, there isn’t a lot of supporting data for the reasons why or how. It may have to do with the specific strain, with stronger body high variations seeing increased effectiveness.

The drug Dextromethorphan has also been connected to the feeling of being high (which we will expand upon below), however, this is only possible if taking abnormally large doses.

Smoking Cannabis While Sick With A Cold Or Flu

While you may not see any ill effects from mixing cold medicine such as NyQuil and cannabis simultaneously, smoking while sick may have its own set of drawbacks. Because many colds come with breathing complications, smoking can further agitate those issues.

If you have a severe cough, triggering that feeling through traditional smoking via a bong, bowl, or a joint may only worsen the feeling. Some have recommended putting ice in a bong, acting to cool the smoke you inhale and giving you a less harsh hit.

Bong manufacturers have even started including built in ice catchers due to the popularity of this trend, although you will be inhaling more moisture into your lungs while you do. Because of the increased moisture, this may also act to agitate your cough, so your mileage may vary with this method.

Can Weed Replace The Use Of NyQuil?

Because of the overlap in side effects between smoking and the use of NyQuil, some may choose to solely rely on cannabis for the treatment of the symptoms. In general, marijuana will not be nearly as effective as a cold medicine when treating all the symptoms, only helping with the sleep aid aspect.

Can Weed Replace The Use Of NyQuil?

Cannabis may also act as a pain reliever, but it will not be as effective as the acetaminophen found in NyQuil. In general, the pain-relieving effects of cannabis will have a shorter duration, with THC remaining active in your system for a relatively short period of time (however it will remain traceable for quite a bit longer, which you can read about here.)

If you have mild symptoms or just a bit of discomfort, cannabis may be a suitable replacement for NyQuil, although it won’t directly treat any of the symptoms of sickness.

Frequently Asked Questions

Should you smoke marijuana while sick?

In general, it is not recommended to smoke while sick with cold or flu-like symptoms. While it may not have any direct adverse effects on your health, it can act to prolong or agitate symptoms of coughing.

If cannabis is a regular part of your daily routine, replacing smoking with edibles, tinctures, or alternative cannabis products can help.

Can NyQuil Get You High?

If abused, many innocuous drugs can promote the feeling of being ‘high’. When taken in large doses, NyQuil becomes one of those drugs, often mixed into drinks with alcohol.

The active ingredient which promotes this feeling is Dextromethorphan, or DMX, which can bring about hallucinations or feelings of euphoria. When these large doses of DMX are taken, the effects are often compared to the illicit drug PCP and is nicknamed “robo-tripping”.

When abused, this can be extremely dangerous, leading to damage of the liver, heart attacks, seizures, or even death. Even if you don’t experience these severe medical conditions, DMX can lead to serious addiction and results in typical symptoms of withdrawal.

Furthermore, accidental addiction can result from nightly use as a sleep aid, so you should remain cautious about the consistent use of NyQuil.
