red life... there's no reason not to change it every time if you have more chore. but id say probably change it every 3 - 5 times you use it would definitely be safe
my question to everybody is: do you think it would work to just get a stereotypical crack stem and fashion a drinking straw and duct tape to one end and have the dmt and chore on the other. or does there need to be more space for the smoke to collect in order to get a good hit?
just to help picturing it:

DMT kinda runs away from the flame alover the glass/crack pipe /stem
I have had good experiences with this method:
