There is cannabis very high in THC, but low in CBD (those are generally the sativa, makes one high) and there's cannabis high in CBD but low in THC (those are generally the indica, makes one stoned). Example source with info at Sensiseeds FAQ (English version) [1]. Quoting (just the effect difference):

"The effect of indica is generally classified as a ‘stone’, meaning that it is more centred on the body. Indicas may enhance physical sensations such as taste, touch and sound.

The indica effect is noted for being physically and mentally relaxing and it may be soporific in larger doses.

Despite their lower weight and potentially longer flowering time, sativas are valued by many growers for their ‘high’ effect.

This high may be characterised as cerebral, energetic, creative, giggly or even psychedelic. It is less overpowering than the indica ‘stone’, and less likely to send the user to sleep."
