Cutting or "stepping on" the drug is commonplace, using compounds which simulate ingestion effects, such as Novocain (procaine) producing temporary anesthesia, as many users believe a strong numbing effect is the result of strong and/or pure cocaine, ephedrine or similar stimulants that are to produce an increased heart rate. The normal adulterants for profit are inactive sugars, usually mannitol, creatine, or glucose, so introducing active adulterants gives the illusion of purity and to stretch or make it so a dealer can sell more product than without the adulterants. The adulterant of sugars allows the dealer to sell the product for a higher price because of the illusion of purity and allows the sale of more of the product at that higher price, enabling dealers to significantly increase revenue with little additional cost for the adulterants. A 2007 study by the European Monitoring Centre for Drugs and Drug Addiction showed that the purity levels for street purchased cocaine was often under 5% and on average under 50% pure. Society and culture
Legal status
The production, distribution, and sale of cocaine products is restricted (and illegal in most contexts) in most countries as regulated by the Single Convention on Narcotic Drugs, and the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances. In the United States the manufacture, importation, possession, and distribution of cocaine are additionally regulated by the 1970 Controlled Substances Act.
One study found that 73% of patients with borderline personality disorder have attempted suicide, with the average patient having 3.4 attempts. The following list includes the disorders that have been shown to be the strongest predictors of suicidal ideation. These are not the only disorders that can increase risk of suicidal ideation. The disorders in which risk is increased the greatest include:
Anxiety disorders
Autism spectrum disorder
Major depressive disorder: 162 
Dysthymia
Bipolar disorder
Attention deficit hyperactivity disorder (ADHD)
Premenstrual Dysphoric Disorder (PMDD)
Post-traumatic stress disorder (PTSD) and complex post-traumatic stress disorder (C-PTSD): 278

Specific learning disorder: 70

Medication side effects
Antidepressant medications are commonly used to decrease the symptoms in patients with moderate to severe clinical depression, and some studies indicate a connection between suicidal thoughts and tendencies and taking antidepressants, increasing the risk of suicidal thoughts in some patients.Some medications, such as selective serotonin re-uptake inhibitors (SSRIs), can have suicidal ideation as a side effect. Moreover, these drugs intended effects, can themselves have unintended consequence of an increased individual risk and collective rate of suicidal behavior: Among the set of persons taking the medication, a subset feel bad enough to want to attempt suicide (or to desire the perceived results of suicide) but are inhibited by depression-induced symptoms, such as lack of energy and motivation, from following through with an attempt.
