- Cocaine can be smoked, snorted, injected or ingested
- Smoked form is often in a free-base or crack form
Detection
- Unreliable in very acute intoxication[1]

- On average, shows up in urine 24-48 hrs after use
- Up to 22 days in chronic users
Adverse effects
- Acute
- Chest pain
- Sympathomimetic qualities
- Tachycardia
- Fever
- Agitation
- Diaphoresis
- Pulmonary Complications:
- "Crack lung"[2]
- Diffuse alveolar hemorrhage
- ARDS
- Pneumothorax
- Pneumomediastinum
- Chronic
- Atherosclerosis
- Cardiomyopathy
- Nasal Septum damage
Mechanism of action
