Scopolamine Can Be Used to Drug People Without Consent

Scopolamine can be used to drug people without their consent, causing disorientation, confusion, and memory impairment, which makes it a potential drug for criminal use. 1, 2

Pharmacological Properties That Enable Misuse

Scopolamine is a potent anticholinergic medication that:

  • Acts as a competitive inhibitor of muscarinic receptors for acetylcholine 2
  • Produces both peripheral antimuscarinic effects and central sedative, antiemetic, and amnestic effects 2
  • Can cause drowsiness, disorientation, and confusion as side effects 1
  • Impairs memory for new information, attention, and feelings of alertness 3
  • Has potential to cause acute toxic psychosis, including confusion, agitation, hallucinations, paranoid behaviors, and delusions in rare idiosyncratic reactions 1

Routes of Administration for Potential Misuse

Scopolamine can be administered through multiple routes, making it versatile for potential misuse:

  • Transdermal (patch) - takes approximately 12 hours for full effect 4
  • Subcutaneous injection - for more immediate effect 4
  • Oral administration - limited bioavailability but faster onset (approximately 0.5 hours) 2
  • Inhalation - can be formed from N-butyl-scopolammonium bromide when burning cigarettes 5

Ethical and Legal Implications

The use of scopolamine to drug someone without consent violates fundamental ethical and legal principles:

  • Violates patient autonomy - a cornerstone of medical ethics 6
  • Constitutes assault or battery under law - touching a patient without consent or approaching with a needle can lead to legal claims 6
  • Violates the requirement for valid consent - which must be given voluntarily by an appropriately informed patient with capacity 6

Warning Signs and Symptoms of Scopolamine Intoxication

Someone who has been drugged with scopolamine may present with:

  • Confusion and disorientation 1
  • Memory impairment, particularly for new information 3
  • Mydriasis (dilated pupils) 7
  • Tachycardia 7
  • Dry mouth 2
  • Blurred vision 3
  • In severe cases, hallucinations and paranoid behaviors 1

Treatment for Suspected Scopolamine Intoxication

If scopolamine intoxication is suspected:

  • Remove any transdermal patches if present 7
  • Consider administration of physostigmine, which can reverse central anticholinergic toxicity 7
  • Monitor vital signs and provide supportive care
  • Be aware that elderly patients may be particularly susceptible to toxicity 7

Special Considerations

  • Variation in response to scopolamine has been reported both between individuals and between different applications on the same individual 3
  • The drug readily crosses the placenta, making pregnant women particularly vulnerable 2
  • Elderly individuals are at higher risk for adverse effects 4
  • The combination with other substances may enhance its effects or create dangerous interactions

In summary, while scopolamine has legitimate medical uses in anesthesia, motion sickness prevention, and palliative care, its pharmacological properties that affect cognition, memory, and consciousness make it a potential agent for drugging people without consent. Healthcare providers should be aware of this potential for misuse and recognize the symptoms of scopolamine intoxication.
