True or False: Mescal is a hallucinogenic Linda takes in the absence of soma?

True 

“I suppose John told you. What I had to suffer-and not a gramme of soma to be had. Only a drink of mescal every now and then, when Popé used to bring it. Popé is a boy I used to know. But it makes you feel so bad afterwards. the mescal does, and you’re sick with the peyotl; besides it always made that awful feeling of being ashamed much worse the next day."
