What is cocaine/crack?

Cocaine is an addictive, stimulant drug which can make people feel more alert, energetic and confident.

Crack is a form of cocaine made by chemically altering cocaine powder to form ‘crystals’ or ‘rocks’ which can be heated to produce vapours that are inhaled.

The effects wear off quickly, promoting the person using to repeat the dose in a binge type pattern that can increase the risks to health.

Crack has a more intense and immediate effect because it is delivered to the brain
much faster than cocaine powder with effects much stronger.


Snorting: Cocaine is most commonly sold as a fine white powder which is snorted. It
can be ground down until the powder is very fine, divided into lines and snorted by using a straw/tooter.

Dabbing “gumming”: Cocaine powder can be consumed by rubbing it onto the gums or by leaving it under the tongue. It is less commonly consumed in drinks or by swallowing orally.

Smoking/piping: Crack is most commonly smoked through a pipe. Using homemade
pipes created from tin cans and water bottles is not recommended. People are advised to contact local addiction services to access approved pipes, if available.

Injecting: Cocaine/crack can be dissolved in water and injected. Among certain user
groups, cocaine is sometimes injected in conjunction with heroin in what is known as a ‘speedball’.

Reduce the harms

It is always safest not to take unknown or illicit drugs at all if a person chooses to take cocaine/crack they are urged to follow the following harm-reduction advice:

If you decide to use cocaine, remember:

  1. When buying, know your source and avoid using alone
  2. Use one drug at a time and never mix with alcohol
  3. Start with a small test dose and leave at least 2 hours between use
  4. Grind cocaine to remove clumps, use your own sterile straw and never share
  5. Carry a condom – cocaine can increase your sex drive

If you decide to use crack, remember:

  1. Avoid using homemade crack pipes and don’t share your pipe
  2. Avoid smoking the full rock
  3. If injecting, start low and go slow to avoid overdose
  4. If you feel low after using, seek professional help
  5. If you or a friend feels suicidal immediately go to a hospital or call 112

Think about your health - Avoid using if you are feeling low, experience mental health problems, high blood pressure, a heart condition or become pregnant.


Cocaine can raise the body’s temperature, cause convulsions, a heart attack or heart
failure. It is possible for cocaine users to die from an overdose. With stimulant type drugs, the risk of overdose increases with the amount used.

The risk of overdosing is also increased if cocaine is mixed with other drugs or alcohol.

An overdose on cocaine is more likely if cocaine is injected.

Recognised consequences of cocaine overdose are:

Cocaine/crack and alcohol

When cocaine and alcohol are used together they combine in the body to produce cocaethylene which increases risk of damaging organs such as the liver and heart. Cocaethylene is more toxic than cocaine and alcohol alone and produces a greater increase in heart rates and blood pressure. Cocaethylene prolongs the effects of cocaine and takes longer to leave the system than cocaine alone. When using both alcohol and cocaine in combination, people risk continuing to drink without realising how intoxicated they are.

Cocaethylene increases the risk of epilepsy, suicide, violence, accidents and sudden death.

Be aware of your use - Take breaks in between use to give yourself some time to recover. Consider talking to a professional if you are finding it difficult to stop using cocaine.
