Which drugs have effects similar to the response evoked during the fight-or-flight reaction?

Stimulant drugs (amphetamine, for example).

Explanation:

Stimulant drugs are substances that increase brain activity as they mimic or cooperate with stimulating neurotransmitters in an individual's body, such as epinephrine and dopamine. Thus, they give a feeling of alertness, disposition and resistance, but that, at the end of their effects, confer tiredness, indisposition and depression, due to the overload that the organism has exposed itself. The effects of these drugs resemble the responses evoked during the fight or flight reaction.

Some of them are: nicotine, caffeine, amphetamine, cocaine, crack and merla.
