Is it safe?

O+ is safe for healthy people of all ages when using the product as directed. As the canister is pressured with a compressed, oxidizing gas, it is recommended that children use it with adult supervision as a safety precaution. People with impaired heart or lung function or other medical conditions should consult with their physician prior to using O+ products. O+ products are for recreational, intermittent use only. Prolonged use is defined as uninterrupted intake for more than 8 hours.
