Inhaling anything at the age of your grandmother should make one VERY CAUTIOUS due to her likely susceptibility to respiratory issues! As well, there are effective oral drugs that can be effective for neuropathic pain, depending on the severity of the neuropathy.

I would disagree 100% with trying "oral drugs first" as numerous studies have shown cannabis to be very effective in dealing with such pain, even when all previous drugs failed. I would highly encourage a vaping experience for her
Partial list:
"Cannabis has been shown to be highly effective at relieving neuropathic pain (Jensen, Chen, Furnish & Wallace, 2015) (Baron, 2015) (McDonough, McKenna, McCreary & Downer, 2014). Two major cannabinoids found in cannabis, tetrahydrocannabinol (THC) and cannabidiol (CBD), activate the two main cannabinoid receptors (CB1 and CB2) of the endocannabinoid system within the body (Fine & Rosenfeld, 2014). These receptors regulate the release of neurotransmitter and central nervous system immune cells to manage pain levels (Woodhams, Sagar, Burston & Chapman, 2015).
In numerous studies, cannabis has demonstrated the ability to significantly lower pain levels in patients suffering from neuropathic that had previously proven refractory to other treatments (Boychuck, Goddard, Mauro & Orellana, 2015). It’s been shown to specifically reduce neuropathic pain caused by diabetes (Wallace, et al., 2015). "

IMO, almost always better to try cannabis first, before big pharma drugs!
