Amphetamine/Dextroamphetamine and Nicotine, a caution.
Nicotine can add sympathetic stimulation to amphetamine/dextroamphetamine and may also reinforce stimulant use patterns. The combination can worsen palpitations, jitteriness, anxiety, insomnia, appetite suppression, and blood pressure or heart rate elevation. Risk is higher with high-nicotine vaping, frequent nicotine pouches, multiple stimulant doses, or underlying cardiovascular disease.

Caution
What is happening. Nicotine can add sympathetic stimulation to amphetamine/dextroamphetamine and may also reinforce stimulant use patterns. The combination can worsen palpitations, jitteriness, anxiety, insomnia, appetite suppression, and blood pressure or heart rate elevation. Risk is higher with high-nicotine vaping, frequent nicotine pouches, multiple stimulant doses, or underlying cardiovascular disease.
Mechanism. Nicotine activates nicotinic acetylcholine receptors on sympathetic nerve endings and the adrenal medulla, increasing catecholamine release. Amphetamine/dextroamphetamine increases dopamine and norepinephrine release, creating additive autonomic stimulation and possible reinforcement of co-use.
Recommendation. Limit nicotine while taking amphetamine/dextroamphetamine, especially around peak stimulant effect. Check blood pressure and pulse if you notice palpitations, chest tightness, anxiety, or headaches. Seek urgent care for chest pain, fainting, severe shortness of breath, or an irregular heartbeat.
