Morphine is described as having high dependency and can be used via which routes?

• A. Orally, Smoked, or Injected
• B. Inhaled
• C. Topically
• D. Orally only

Answer: (A)

Morphine’s strong potential for dependence is tied to how quickly it reaches the brain, with rapid-onset routes carrying the highest abuse risk. Injecting morphine delivers an almost immediate effect, and smoking it achieves a rapid CNS hit as well, both of which reinforce compulsive use. Oral morphine remains clinically used and does carry dependence, but its onset is slower due to digestion and first-pass metabolism, so it’s included alongside the faster, high-risk routes. The other options don’t capture this combination: inhaled alone isn’t a standard, clearly defined route for dependence, and topical administration mainly provides local or limited systemic effects. So, describing morphine as usable by oral, smoked, or injected routes best reflects its pharmacology and how dependence can develop.
