Is this safe?

I am 5wks nearing 6wks my bf was asking if I'd be able to roll up some devil's lettuce and grind it. I will not be smoking it or being near it besides that. Please be kind I'm sure it's a stupid obvious question but it's my first time being a mom and Everytime I tried to Google it would just say it's bad to smoke or digest WHICH I WILL NOT DO.
