Editing Cocaine (section)

==== Injection ====
Subjective effects not commonly shared with other methods of administration include a ringing in the ears moments after injection (usually when over 120&nbsp;milligrams) lasting 2 to 5&nbsp;minutes including [[tinnitus]] and audio distortion. This is colloquially referred to as a "bell ringer". In a study of cocaine users, the average time taken to reach peak subjective effects was 3.1&nbsp;minutes.<ref name="Volkow" /> The euphoria passes quickly. Aside from the toxic effects of cocaine, there is also the danger of circulatory [[embolism|emboli]] from the insoluble substances that may be used to cut the drug. As with all injected [[illicit substances]], there is a risk of the user contracting [[Blood-borne disease|blood-borne infections]] if sterile injecting equipment is not available or used.
