Understanding drug origins and effects supports informed therapeutic use.
Statement I: "Morphine is obtained by acetylation of Heroin" - Incorrect. Heroin is produced by acetylation of morphine, not vice versa.
Statement II: "Cannabinoids affect cardiovascular system" - Correct. Cannabinoids, particularly THC (tetrahydrocannabinol), can affect the cardiovascular system. The effect varies and may include increased heart rate, changes in blood pressure, and potential risks for individuals with pre-existing heart conditions.
The correct evaluation is: (C) Statement I is incorrect and Statement II is correct.
Statement I: Morphine is not obtained by acetylation of heroin. In fact, heroin (diacetylmorphine) is synthesized by acetylating morphine. Acetylation of morphine makes heroin more potent and lipophilic.
Statement II: Cannabinoids (compounds found in cannabis) primarily affect the nervous system, particularly by binding to cannabinoid receptors. They can influence pain, mood, and appetite, but they do not primarily affect the cardiovascular system.
Option (C) is correct because Statement I is incorrect, and Statement II is correct.
