Here's what Jim Cramer had to say about some of the stocks that callers offered up during the "Mad Money Lightning Round" Friday evening:

Cronos Group (CRON - Get Report) : "I think Canopy Growth (CGC - Get Report) is best. This one is second best."

Invitae (NVTA - Get Report) : "If you want targeted cancer treatments, this one is a buy."

Fortinet (FTNT - Get Report) : "This is a tough one. I like Palo Alto Networks (PANW - Get Report) a lot more."
