Great question, Don! I have practiced meditation most of my life. The only drawback to meditation is how it is used. If one is using it to calm the mind, to regain focus, or for spiritual connection, this is healthy.
If meditation is being used as a form of retreating from the daily stresses of life or hiding from emotions, then we must examine if this is withdrawing from social norms or addiction, which are attachments to the process and not the outcome.
Healthy meditation is balancing, quieting, and meant to relax the mind to better cope with our emotions that arise from our worldly experiences.
