People put their hands on Van de Graaf generators[1], people buy electric shock buzzers from joke shops[2], people stand on body-fat measuring scales which send electric current through your body to measure its conductivity and estimate fat content, people touch vehicles on humid days and get static electric shocks, people use electric shock to the brain as a therapy[3].
The safety risks I'm aware of are alternating current across your heart strong enough to override the heartbeat signals and make it quiver instead of beat normally (e.g. touching mains power with both hands, current flow through the chest), and enough current flow to cause flesh burns (extreme examples: lightning strike, touching electricity substations). I'm not aware that "feeling a buzz" is inherently a safety risk without any more context or explanation.
