Snorting & swallowing drugs

Snorting drugs – how it works

When you snort drugs, they are absorbed through the lining of the nose into the bloodstream, then to the brain, where effects begin quickly.

The effects start quicker, are more intense and end sooner than swallowed drugs, with a harsher comedown.

Snorting constricts nose blood vessels, reducing oxygen and causing mucus production, felt as a throat drip and runny nose.

The more you snort, the more snot is produced — and the less of the drug gets absorbed. Snorting more often makes each line less effective.

The risks of snorting drugs

Snorting stimulant-type drugs restricts blood flow inside the nose. Combined with the corrosive qualities of the drug or what it’s cut with, this can lead to nosebleeds and permanent damage.
Damage and bleeding inside the nose make it easier to pass on viruses like hepatitis C, especially when sharing snorting tubes. A microscopic drop of blood — too small to see — is enough to infect someone.
Some new or emerging drugs are particularly damaging to the nose because of the harsh chemicals used in their preparation.
Small changes in dose can cause big differences in effect, making snorting riskier and harder to control.

Reduce the risks from snorting

Flush your nose with water after each session or line to reduce damage from corrosive effects.
Use a nasal spray or snort clean water from cupped hands, then blow your nose.
Chop powder as fine as possible — this causes less damage and improves absorption.
Never share snorting tubes or banknotes. Use your own tube or stick to a key or clean finger.

Swallowing drugs (bombing) – how it works

Swallowing is one of the simplest and oldest ways of taking drugs. The drug is absorbed through the stomach and small intestine into the bloodstream. It then passes through the liver, where some is filtered out, before reaching the brain.

Swallowing takes longer to kick in — effects may not be felt for 30 to 45 minutes, especially if you’ve eaten recently.

Powdered drugs are often wrapped in cigarette paper before being swallowed — a method called bombing or parachuting. Some people mix powder into hot drinks instead.

The risks of swallowing drugs

If you don’t feel effects and take more too soon, there’s a risk of overdose.
Stimulants can reduce blood flow to the gut, increasing the risk of ulcers or internal damage.
Long-term use can affect the stomach, intestines, liver and kidneys. If you have liver problems, swallowing drugs can be especially risky.

Reduce the risks from swallowing

Start with a low dose and wait. Don’t take more just because effects are delayed — drugs can vary in strength or be mixed with other substances.
Eat something beforehand to reduce stomach irritation.
Liquids like GHB and GBL should always be diluted before use — and some, like poppers, should never be swallowed at all.

Additional questions about snorting and swallowing drugs

The information you've just read comes from our printed snorting and swallowing drugs leaflet. The details below take a deeper dive and add extra context, drawn from common questions people ask and popular searches on our website.

Can you snort MDMA and Molly?

Yes, it is possible to snort MDMA, whether it is in powder/crystal form ("Molly") or a crushed pill.

Snorting makes the effects hit faster and feel stronger, but they wear off sooner. This rapid rise and fall can lead to a harsher comedown and an increased urge to use again.

Snorting powder gives you some control over the amount of drug you are using because you can decide how much powder to use, but small changes in amount can cause big differences in effects. Start with a small amount and wait until you see how you feel before using it again. Remember, you can’t actually be sure how much of the drug is in an amount of powder, or if it contains a substance you’re not expecting, so go low and slow.

You can snort MDMA by either crushing up a pill or using the powder form known as Molly. Both come with the same risks to your nose and the usual contaminants or adulterants that dealers add. Pills also contain fillers and binders, which can make snorting crushed pills an unpleasant experience.

Molly is simply MDMA in powder or crystal form. It’s the same substance that’s pressed into pills. Some people think Molly is “purer,” but there’s no evidence for that. Powder can be just as easily mixed or cut with other drugs as tablets, and you can’t tell purity by looking at it.

Remember: wash your nose out after a session, don’t share straws or notes, use a small amount and see how you feel before using again.

Does ketamine work the same if you put it in a drink instead of snorting it?

Taking ketamine by mouth works differently than snorting it:

How it affects you:

Slower to kick in
Generally less intense experience
Still causes bladder damage — same as snorting

If taking orally:

Crush into a fine powder for better absorption
Wrap in paper (bombing) or mix into a non-alcoholic drink
Mark your drink clearly so no one else takes it by mistake

Important safety points:

Start low and wait at least 2 hours before re-dosing
Never leave your drink unattended
Don’t drink from unmarked containers
Mixing with alcohol increases all risks

Why do people snort drugs?

Faster effects: Snorting bypasses the stomach, delivering drugs straight into the bloodstream via the nose lining. Effects are usually felt in minutes.
Dose control: People can take smaller amounts gradually and stop if needed. Swallowing commits you to the full dose at once.
Stronger absorption: Less of the drug is broken down in the stomach and liver, meaning more reaches the brain.
Less nausea: Some avoid swallowing drugs because of stomach sensitivity or nausea.
