Final answer:
Gilbert, who has consistently used cocaine, might report heightened feelings of euphoria and increased confidence while high; however, chronic use can lead to more negative effects including severe mood swings and increased irritability.
Step-by-step explanation:
If Gilbert has used cocaine consistently for the past couple of months, he might report heightened feelings of euphoria and increased confidence, which are typical effects of the drug while a user is high. However, the effects of cocaine use vary depending on several factors, including the amount used and individual reaction. Cocaine is known to cause vasoconstriction, which can increase blood pressure. Other acute effects of cocaine include increased energy levels and sometimes reduced anxiety due to its stimulant properties. Chronic use, however, can lead to severe mood swings and increased irritability, especially as the effects of the drug wear off. Moreover, over time, addiction and dependence can result in tolerance, meaning that more of the drug is required to feel the same effect, and discontinuation can lead to withdrawal symptoms such as depression and fatigue.
