Hi @raulp! Thanks for commenting.
Smoking is the best way to control an anxiety attack when it's happening.
Many ingestion methods are available if someone wants to use cannabis as a preventative to anxiety attacks.
As I decarbed this oil, it can be eaten. Someone eating it for the first time, would start with an amount equivalent to 1/2 a grain of rice and it would work nicely. Doing some strain research is a good idea. There are strains that can cause anxiety attacks so if a person is prone to them, they shouldn't use those particular strains.
