Estupefacientes o psicotrópicas productoras de dependencia física o síquica, capaces de provocar graves efectos tóxicos o daños
gladu [14]

Answer:

Drogas.

Explanation:

Las drogas son sustancias que tienen un efecto modificatorio sobre el estado normal de la psique. Por tanto, estas sustancias influyen en el comportamiento o la experiencia del usuario, pudiendo tener un efecto alucinógeno, pero también sedantes o una mixtura entre ambos.

El término se usa generalmente para indicar sustancias que tienen un efecto muy fuerte (por ejemplo, heroína, cannabis, mescalina, alcohol). Aunque los estimulantes cotidianos como el café y el chocolate también pueden tener un efecto en la psique, generalmente no se clasifican como sustancias psicoactivas debido a su efecto relativamente leve.

Los medicamentos que tienen un efecto sobre la psique se denominan psicofármacos. No obstante, los medicamentos que no se clasifican principalmente como psicofármacos, como los antihistamínicos, los agentes anti-mareo y los betabloqueantes, pueden también tener un efecto psicotrópico.
