Make sure to insert the straw high up into the nasal passage before snorting. This reduces the amount of cocaine that gets trapped by nose hairs. Cocaine left in the nostril can lead to irritation and a damaged septum - and ultimately to a perforated septum.
Alternate snorting sessions between both nostrils and after snorting, rinse out your nostrils to clean off any cocaine adhering to your septum. Try water or saline in a spray bottle for this. Make sure to chop up into a very fine powder.
Reducing Injection Risks
If you don't already inject, don't start. If you already inject, switch to safer modes of administration, like smoking.
Cocaine injection is riskier than opioid injection since cocaine users inject more frequently (due to cocaine's shorter high) because cocaine acts as a tissue damaging anesthetic and because since it's an anesthetic, you can't always feel the damage you do.
If you choose to inject, to avoid re-using syringes and damaging veins, make sure you have enough injection equipment on hand. If getting from a harm reduction center or needle exchange, tell them you inject cocaine and therefore need a larger supply. Take care of your veins and maintain good injection practices to reduce infection risks. Read our harm reduction guide to heroin injection for a more complete list of safe injection tips.
If you can Switch from injecting to smoking or snorting - or at least avoid injecting in very risky sites, like the groin or neck. If you get to the point where you need to rely on very dangerous points, it's time to stop injecting.
Avoid skin popping. Cocaine isn't easily absorbed into tissue and can lead to constricted blood flow and tissue damage. Under-skin tissue damage can lead to discoloration at the injection site.1
Reducing Smoking Harms
Don't share pipes. Sharing pipes or stems can lead to the transmission of HIV, herpes, hepatitis and other diseases.
To prevent cuts and burns, wrap stem ends with tape or rubber.
To avoid hand burns, buy a good lighter. A burner type, rather than a flame type, may be preferable, since you'll avoid inhaling the heat from a close flame.
Treat lip cuts and burns with a water-based lip balm. Don't smoke from drink bottles or cans. This can lead to lung damage through the inhalation of ash, paint and toxic dust (a glass pipe is a much safer alternative).
Use a wire screen in your pipe to prevent the inhalation of hot particles. Let the pipe cool down between hits. If chasing, use real tinfoil and not foil from packaged foods like candy bars. This type of foil can have harmful contaminants.2 Get medical attention at the first signs of lung damage (don't wait until it's too late). See a doctor if your breathing is wheezy or painful after a session. Because of crack's anesthetic properties, you often can't feel lung pain until after the drugs wear off.
Avoiding Infection
Don't share snorting straws. Minute (invisible) flecks of blood are often present and these can confer HIV or hepatitis C between users. It's not just the syringe, you can't safely share any injection gear; use your own cooker, cotton, tie and water too. Don't use a rolled-up bill to snort with. These bills are far from sterile and can transfer many common infections when inserted against the mucous membranes of your nasal cavity. Carry and use condoms. Cocaine can make you rock hard :D. Get a hepatitis B vaccine or booster.
The Come Down :(. Think about how to ease the discomfort of the crash. Know that the worst part of the crash only lasts for 45 minutes to an hour. Try relaxation techniques to calm down during the crash. Some people find eating after a binge can help get you feeling better.
Avoid using alcohol during the crash.
If your binges tend to get out of control, limit your access to cash before you begin a session so you won't end-up with nothing to pay the rent.
You might try asking a freind to hold onto your money for a while or leaving with only a set amount of money and no ATM card.

great info.... a cocaine grinder is a great cheap tool to help get a fine powder (ebay hand powder grinder ) ... i would also suggest a metal tool for the nose to help get the fine powder past your nasal cavity
