The statement is - True.
The solvent do contains chlorofluorocarbons (CFC) and hydrochlorofluorocarbons (HCFC) which evaporate and enter the atmosphere. Because they are very light, the CFC and HCFC manage to get very high into the atmosphere, reaching the ozone layer in the stratosphere. They are actually the two substances that are the most damaging to ozone layer, as once they get in touch with it, they break down its structure, thus creating the ozone holes.
The ozone is crucial for the survival of the living organisms on the Earth as it is the layer that manages to stop most of the ultraviolet rays form the Sun to reach the surface. Because of that, these two substances have to be replaced quickly as the ozone layer is becoming more and more damaged, and that can eventually lead to a tragedy.

Abstract
Nitrous oxide has been used therapeutically as an anesthetic and an analgesic for more than 100 years. The anesthetic effect is thought to be mediated primarily by the reversible inhibition of the N-methyl-d-aspartate type of glutamate receptors resulting in inhibition of excitatory glutamatergic neurotransmission. Nitrous oxide exerts it analgesic effects via activation of opioidergic neurons. Most significant human exposure to nitrous oxide occurs in medical settings either by therapeutic administration or as unintended exposure:
